DEAR HARRIETTE: I joined a dating app a couple of months ago, and I connected with a really nice man who met all of my requirements. It wasn't until about two weeks ago that he started showing serious signs of instability. For example, if I’m busy and cannot answer my phone, he will call and text me incessantly. He’s even gone as far as to call my work number and make sure I’m there. On one occasion, he showed up at my house unannounced and practically begged me to let him inside. We are not even officially in a relationship -- we are only casually dating. I don’t know if I can look past this behavior. Should I have a talk with him or just cut him off altogether? -- Online Dater

DEAR ONLINE DATER: This man sounds dangerous. You definitely don’t want to keep dating him, but because he knows where you live and work, you have to be careful in distancing yourself from him. If possible, have a conversation with him on the phone and let him know that while you have enjoyed getting to know him, you do not want to go out with him anymore. Assure him that he is a nice guy, but you have decided that you do not want to continue this relationship. If he asks why, tell him that you don’t think you two are a good fit. Before you get serious, you want to stop.

Chances are, this won’t be enough. You should alert your neighbors, friends and job that this man may decide to lurk around, and you need them to have your back. You can contact the dating app and let them know that this man has some stalker tendencies. If he crosses the line -- as in trespassing or threatening you -- call the police.

DEAR HARRIETTE: My sister is a year older than me, and we grew up very close. We were roommates in college, and our kids were even born within the same year. When I moved away to a different state, we gradually grew apart.

When our kids were younger, we would spend holidays together, but now our kids are older and they all have their own lives. There's a lot of tension between my sister and me because I know she feels a bit excluded. What makes things more challenging is that when I do reach out to her, she seems to be upset with me. I would like to rebuild and strengthen my relationship with my sister. Life is too short to fight with the people you love. How can I fix our strained relationship? -- Sister Problems

DEAR SISTER PROBLEMS: Ask your sister to have an honest talk with you. Invite her to tell you what’s going on with her. Point out that she always seems to be upset with you when you talk, and you want peace in your relationship. Coax out of her what’s really going on. Whatever comes up, try to address it head-on. Remind her that you love her and her children and want more than anything to work together to release the tension and reclaim the tight bond you once shared.

DEAR HARRIETTE: My best friend and I have been neighbors for 20 years. For 20 years, she’s been a short walk away from my home; she’s always been there whenever I’ve needed her (and vice versa). Recently, she told me she accepted a position in another state. Although I'm happy for her, I'm devastated that she is moving so far away from me. I'm excited for her to start this next chapter of her life, but it's hard for me to be happy for her knowing that I'm being left behind. How can I be a supportive friend without showing how truly sad I am that she is leaving? -- Losing My Friend

DEAR LOSING MY FRIEND: You two are close, so it’s natural that you would be sad -- devastated, even. It’s also OK to tell her. Chances are, she is feeling emotional about this change in her life, too. What you probably need is to have a good cry with her, swap stories about wonderful memories that you have created together, and help her pack.

Many dear friends are close even when they live many miles apart. This can be true for the two of you. You can still visit each other. Don’t consider this goodbye. Instead, think of it as a new chapter in your lives.

DEAR HARRIETTE: I can't stand my boyfriend’s taste in music. Music is extremely important to me, as I am a recording artist. I believe that music reflects your soul and who you truly are. There isn't a single song that I've played for him that he's liked; he doesn't even like the music I make. I'm not offended that he doesn't like my music because it doesn't tend to attract his demographic anyway, but I'm afraid this is the beginning of a deeper issue for us. I don't like the fact that we can't bond over something as simple as music. Do you think this is a sign of a deeper issue? -- Songstress

DEAR SONGSTRESS: I remember when I met my husband and began to listen to the music that he likes. It was so different from my musical choices. Some of it I liked; some, I didn’t. Now, nearly 30 years later, our musical tastes remain very different. Sometimes when he is listening to his favorite radio station in the car, I pop in my headphones and listen to something else. Often, we take turns listening to each other’s channels when we are driving long distances. The point is: We figured out ways to compromise without judgment. We accept that we like different things.

If you two can come to that agreement and be willing to listen to each other’s music from time to time, it may not become an issue for you. The one trouble spot may be the fact that your boyfriend doesn’t like your music. But even that can be overcome. We don’t always like, understand or appreciate our partner’s work. As long as you two can avoid passing judgment, you can work it out.

DEAR HARRIETTE: I’ve recently started dating a woman who is a lifelong vegan. She is very health-conscious, and she even has a website and YouTube channel dedicated to her plant-based lifestyle. While I admire her dedication to veganism, I myself have never been a vegan, nor do I wish to be.

My girlfriend has “joked” a few times about how she plans to convert me into a full-fledged vegan. Whenever we go out to eat, she gets upset if I choose a meal that has meat in it. I’ve never liked being told how to live my life or feeling like someone is forcing their ways on me. I don’t appreciate the judgment she passes whenever I eat what I want to eat. How can I fix this? -- Non-Vegan

DEAR NON-VEGAN: You two need to have a serious conversation about values and boundaries. Explore what values and beliefs you share. Where do your ideas about life sync up, and where do they not? Talk openly about your beliefs, and consider whether your differences are manageable or too far apart. Talk about the way you eat in this context. It is possible for the two of you to be in a relationship when you don’t eat the same foods, though it won’t be easy. It may require that you both cook, for example, so that when you eat at home, you each get to enjoy the food that you prefer.

You need to directly address her judgment over your eating habits. Explain that you know that her food choices are important to her and you would never stand in her way, but you expect the same respect for your choices. Be clear that you do not want to become a vegan, and you want her to stop proselytizing. Now, if you eat in an unhealthy manner and your body needs to get well, you may want to talk about ways to improve your eating -- but without the judgment.

DEAR HARRIETTE: My daughter recently told me that she wants to move out of state by herself. She just graduated from college and is very independent, but I really want her to stay closer to home without clipping her wings. When I graduated from college, I was engaged to be married, so I left home and moved to a different state from my family, and I deeply regret that. I know that these are different times, but I would still like her to stay close to home. How do I broach the subject without making her feel that I am stopping her from exploring her adult life? -- Empty Nest

DEAR EMPTY NEST: Your job as a parent is to prepare your child to become an adult. That means that you give her the wisdom and knowledge about how to take care of herself without your supervision. This is hard for parents sometimes because on one hand, we want our kids to grow up, but on the other, we want them to stay close to us.

You have to prepare to let go -- now. Allow your daughter to make her own decisions. Let her move wherever she wants to move, and give her your blessing. You can tell her that she is always welcome to come home and that you will miss her terribly, but you have to encourage her to make her own decisions. Do not talk about your regrets right now. That will guilt her. Let her go.
