DEAR ABBY: My mother is 80 and living alone after my dad passed. Her memory is failing. She recently fell and required shoulder surgery. This wasn't her first fall; she has also broken her hip within the past four years.

I installed a camera in her den so I could periodically check in to see if she was OK. I didn't tell Mom about the camera because I knew she wouldn't agree. My intent was only to be able to check in on her. I try to visit her at least four times a week.

Recently, when I viewed the video, I overheard a conversation between her and my brother. During the conversation, she made a lot of negative comments about me, related to my being authorized on her checking account. Abby, my income is in the six figures, and Mom lives on $1,400 a month. It was extremely upsetting because I have tried hard to make sure she had what she needed.

I can't begin to tell you how much hearing the negative comments she made hurt. My mother has never been a loving person; however, I continue to make great efforts to do the right thing when it comes to her. What is your advice? -- DUTIFUL DAUGHTER IN ALABAMA

DEAR DAUGHTER: Your idea of installing the security camera was a good one, considering the fact that she has become accident-prone. Have a talk with your mother. Tell her, without revealing that you have the camera, that you love her but think it is time for your brother to assume the responsibility of taking care of her financial affairs. It will be interesting to see how she reacts to that suggestion. If she is fine with it, you will know it is time to step back.

DEAR ABBY: I am a grandmother of three and was particularly close with one of the girls. When she was younger, she'd come to visit for months at a time. (We live in different states.) She seemed to change when she was in college. Because I wasn't hearing from her, I asked her mom how she was doing.

When she heard about my inquiry, my granddaughter got very nasty. She said that I should ask her if I want to know anything about her and to keep her mother out of it. When I explained that I only asked her mom because I don't hear from her, she blocked me from her social media and no longer returns my messages or phone calls. I miss her and the relationship we had very much. Should I let it go or keep trying? -- HEARTBROKEN IN THE SOUTH

DEAR HEARTBROKEN: Your granddaughter may not have wanted her mother nagging her about not having enough contact with you, or she wasn't comfortable having her mother act as go-between. She also may feel entitled to a private life.

Ordinarily, I would suggest that you write or call her and apologize. However, since she has blocked those means of communication, try putting your thoughts into a letter (with a stamp on it) if you have her street address. If that fails, you may have to wait to communicate with your granddaughter until she grows up enough to recognize that she overreacted.

DEAR ABBY: I just left a verbally and physically abusive relationship. I suffer from mental illness, and "Scott" made it worse. We lived together for almost four years. I could beat myself up over deciding to live with him. He's an alcoholic, narcissistic, bipolar, sociopathic liar who swears he's a man of God. Scott kicked me out countless times during the time we lived together, knowing I had nowhere to go. Five months ago was the last time.

I still love him and care for him, but I learned last month that he met someone at AA and took her in. She had been living with him until yesterday. We were still "together" until two weeks ago but without any romantic encounters. I am torn to pieces over this man. It has taken me over and who I was as a person.

Scott has a history of abuse. He has a criminal record for killing an animal when he was staying with someone. I didn't stay clear of him because I was sucked in by his charm. I am now living with a friend and seeing a psychiatrist and a therapist who are doing NOTHING for me! Scott and I were engaged. We were going to get married pending his being sober for a year, which never happened. I don't know what to do. Please help. -- BROKEN WING IN MINNESOTA

DEAR BROKEN WING: As I read your letter, I hear the strains of Cole Porter's "So in Love." PLEASE look up the lyrics because they describe you accurately. What you need to do is continue talking with your therapist and getting meds from your psychiatrist until they help you undo your fixation on someone who, if your description of him is accurate, is a sociopath and incapable of loving anyone. Until you can do that, your story will not have a happy ending.

DEAR ABBY: I am a 66-year-old woman, married with two daughters. I am also 5-foot-2 and weigh 108 pounds. This is not something new. But whenever there is a gathering with my in-laws, at least one of them says I need to put meat on my bones -- in those exact words. I think it's rude and offensive. I am certainly not telling any of them to take meat off their bones.

I cannot help my size, metabolism or genetics, and I am tired of the comments. These people have known me for 39 years. I have always been this size. I don't know what to say to them. I no longer care anymore about being kind. -- SLIGHT IN OHIO

DEAR SLIGHT: If you really don't care about offending the offenders, take off your kid gloves. Tell your in-laws you have tolerated their comments for too long and to quit doing it because you don't like it. If, heaven forbid, they say you are "too sensitive," ask them how they would like being told they are too heavy and that their perfume smells like garbage. (I'm sure you can think of something once you stop laughing.)

DEAR ABBY: My niece-in-law, "Justine," is a few years younger than my husband and I. We have been best friends for the last 25 years. She's 55 and divorced, with a grown daughter but no man in her life. She's extremely lonely and has only us as emotional support.

During the last year, she has had to move her 78-year-old mother (with whom she has a tumultuous relationship) in with her. Justine's daughter has distanced herself from her mother because Justine has erratic moods. Recently, she sent me a four-page letter saying how angry she was with me and my family about things that never happened. She invented transgressions, insulted my grown children and targeted my daughter-in-law. My son is furious.

My husband, who loves Justine and feels like an older brother, says he wants to repair our family. I love my husband, but my first allegiance is to my kids, and I'm surprised and hurt that he isn't furious with her for attacking me with untruths. He says we have to find a way to get past this. (She didn't include him in her letter.) I'm trying to be prepared for upcoming family gatherings. What can be done to repair this? -- LOOKING FOR A WAY IN THE SOUTH

DEAR LOOKING: If Justine is inventing things that never happened in order to justify her anger, the chances are great that she is mentally ill. Until she is willing to recognize that she is driving away the people who care for her the most, things may get worse. Suggest to your husband that if he can convince Justine to get the help she needs, you are prepared to forgive her for the hurt she is causing. Then all of you should cross your fingers and hope that she sees the wisdom.

DEAR ABBY: My older sister thinks she's better than me. She makes little snide comments and thinks it's OK. It has led to a couple of big arguments in the past seven years. The last argument was over some money I was missing. She's been stealing from anybody and everybody -- from hospitals, doctors' offices, family members and her boyfriend's family. When I realized that she had stolen money from me as well, it was the last straw. I confronted her, and her response was I am now "dead to her." We haven't spoken in several months.

Her boyfriend died last week, and she hasn't told me. (I found out on social media.) Should I reach out to her about funeral arrangements or contact his family instead? His family never really talked to any of us. They didn't like her because they thought she was only there for his money. -- OUT OF THE LOOP IN ARIZONA

DEAR OUT: Unless you feel the need to attempt to make up with your troubled sister, do not reach out. However, if you want to do something for the boyfriend's family, send them a nice condolence card expressing your sympathy.
