DEAR ABBY: I moved away from my ex-boyfriend, "David," seven months ago. Since then, our "perfect" relationship has changed drastically. He has been using horrible language toward me and saying he hates me. David also has said if I was near him, he would beat me. Now that I have told him it is over and have begun talking to someone else, he has decided he wants a second chance.

First, David begged me to go back to him. Then, when I refused, he threatened to ruin my life. He knows some things about me that are very confidential and has threatened to call my mom and tell her everything. He claims he loves me, but then he tells me he hates me.

I don't understand. I have always treated David with respect and tried to be a good girlfriend. But I can't do it anymore, and I'm afraid of how things will turn out. I can't take David harassing me. I don't know if I am in danger or if this is something to worry about. -- SCARED IN SOUTH CAROLINA

DEAR SCARED: People who love each other do not treat each other the way you are being treated. Your ex-boyfriend has become obsessed, and is trying to force you to capitulate through intimidation and blackmail. Tell him once more that it is over and you want him out of your life. Then screen your calls, block his e-mails, and if he approaches you, tell him that if he persists you will inform the police. And if you must, beat him to the punch and tell your mother what he's holding over you. It may not be your proudest moment, but it will loosen his hold over you.

P.S. Under no circumstances should you reconcile with him. This is just a taste of what you'll get if you do. If the harassment continues, go to the police and file a report.

DEAR ABBY: I have always been an animal lover. I have had a peek-a-poo, "Flopsy," for 12 years. She's the last of my pets, and loves me as much as I love her.

Flopsy was hit by a car and her hip was fractured. Now I must confine her to our house until she's well. My fiance, "Lenny," complains I have spent too much money at the vet on her. Lenny says he can put a 20-cent bullet in her and solve the problem.

Of course, I would never permit it, nor will I do anything like that. Flopsy doesn't bother him. She always stays in the same room as me no matter where I go. I have no demanding chores in my life, so I don't see the harm.

Do you think I should put her out of her misery? Am I being selfish? -- ANIMAL LOVER IN GEORGIA

DEAR ANIMAL LOVER: You're asking me something that should be discussed with Flopsy's veterinarian. If, at her age, she can regain her health and mobility and frolic again, I see no reason to euthanize her. If she can't, then it might be the kind thing to do.

Something else in your letter concerns me, however. The relationship you have with Flopsy apparently does "bother" your fiance. I suspect that he resents the love you have for her and the time and attention you lavish on her. To have suggested "putting a bullet in her" shows he has a cruel streak. If you are wise, you will think long and hard before marrying someone like that.

DEAR ABBY: My husband of five years, "Jeff," is one of the most intelligent, loving, sensitive men I have ever met. However, the other day, my daughter, "Julie," reported that Jeff had touched her inappropriately two years ago when she was 10. She also quoted some inappropriate sexual comments he has made and said he had even flashed her once.

As if that is not bad enough, she said Jeff had also been threatening her while I was at work, saying things like, "Your mother isn't here to save you." He has never hit either one of us. He is all bark and no bite, although he can be very scary when he is angry.

The police and the Department of Human Services are now involved. Jeff has moved to a motel pending an investigation.

I know my first concern should be for Julie, but I feel she is safe and happy. I am more upset about my husband. Even though I know he is an idiot for doing these things, and my daughter is afraid of him, I don't think he ever intended to molest or hurt her. But he has.

So why do I want him back so much? I am afraid the detectives will force me to divorce him. I know Julie is not comfortable around him, but I keep hoping that family counseling and some therapy will solve the problem. Of course, I will always choose my child first, but when do I know when to give up on my marriage? -- TORN IN TWO IN OKLAHOMA

DEAR TORN: You probably want your husband back because you are still in a state of denial, or have not yet accepted the fact that he may have married you to get to your little girl. You will know when to give up on your marriage when you have finally accepted that you married a predatory child molester who tried to bully your daughter into submission. She is afraid of him for good reason, and family counseling and therapy are not likely to "cure" him of his sick fixation on her. Please remember that when he tries to re-ingratiate himself.

DEAR ABBY: From time to time, you tell young women who think they might be pregnant and are afraid to tell their parents, to do so. I usually do not write letters like this, but I need to express my personal experience. I am a minister. Several years ago, I worked for Planned Parenthood and we had a young girl -- around 13 years of age -- test positive for pregnancy. We urged her to tell her parents, but she kept refusing, insisting, "Dad will kill me!"

Of course, we knew better, and finally convinced her that the best thing was to tell her parents, have the baby, and get on with her life.

Her father beat her so badly that she was in the hospital for more than a month. She lost the baby because of the beating and ended up in foster care.

I will never again tell a young person that her parents will not go crazy, and I don't think you should do that either. Thanks, Abby. I enjoy your column. -- REGRETFUL IN FLORIDA

DEAR REGRETFUL: Thank you for the warning. Even though we wish all teenagers could disclose to their parents, as your letter illustrates, it is a sad reality that some of them cannot. And we, who care about young people, have to first be concerned with their safety. Although most young girls do involve their families, there will always be some who are unable to do so.

For that reason, I do not believe that parental notification should be mandated by law. And because sex education is no longer taught in as many states as it had been before, I strongly urge parents to begin talking to their children early about the facts of life and their personal value systems, in order to create a safe and comfortable environment should a crisis occur.

DEAR ABBY: From time to time I have seen letters in your column about acts of kindness. I hope you will print my letter to say "thank you" to a kind soul who helped me after Hurricane Katrina.

My husband and I stayed in our home in Biloxi during Katrina. We were fortunate that the storm stopped at our front door. The large oak trees that fell did not fall on our house, and we were able to assist others on our street who also stayed. But we both knew that I needed to get our children (3 1/2 years old and 15 months) out. We were running short of water and were not sure when there would be more food.

Not realizing how badly everyone had been affected, I left the house with only two small bottles of water, $10 in cash and a few snacks. I wanted to leave everything for my husband -- thinking that as soon as I got to Jackson, Miss., everything would be fine.

I arrived in the town of Hazelhurst on Tuesday evening with two thirsty, crying babies, and wondering what in the world to do. I pulled into the Days Inn and asked if they had a room. They did, but there was no water, no electricity and no drinking water. I left the front desk in tears.

A kind Hispanic woman ran after me and offered me a gallon of her water. I offered her the $10, but she refused it. Her husband told me I needed to stop and rest. She helped me take the kids out of the car, helped me with my luggage, helped me check in, and showed me to my room. Later that night, she brought me half a gallon of milk for the babies, and a beautiful votive candle so I could see them. She said, "For the babies."

I left early the next morning to try to get enough gas so I could reach my parents, and I never got the woman's name. May God bless her for the rest of her life. I am normally very logical and calm, but I could not think clearly that day. She opened her arms and her heart, and for that I am truly grateful.

I wish I could see her, hug her and say "thank you" in person. I owe her so much, but all I can offer her are my prayers for the rest of her days on this Earth.

Thank you for helping me try to reach her, Abby. God bless all of us in this difficult time. -- LAURA V., BILOXI, MISS.

DEAR LAURA: I'm pleased to print your letter. I hope your guardian angel sees it. By sharing what little she had with you, she demonstrated the true spirit of giving in its highest form.
