Anna: I would deal with this problem immediately. You don't want this negative image of her to build up in your mind, to a point where you can't take it and you just suddenly stop talking to her or worse, snap at her. You have to lay it down for her that she's already hurting people, which crosses a lot of lines already. I highly doubt she doesn't think she's doing absolutely nothing wrong but you know, there are some people who are so oblivious to their insensitivity. Just talk to her, alone. Never gang up on her unless she doesn't want to listen the first time. Also make it private because you're a decent human being who doesn't call people out in public to shame them.
"Something's wrong with my boyfriend and I don't know what. He's kind of pulling away and won't talk about stuff anymore. He doesn't text me that often and we don't see each other as much as I want to. I feel like he's grown tired of me and he doesn't like me anymore. I don't know how to confront him about it because I might just be assuming things but I can really feel a weird vibe between us. Pls help because I really like him and we've been together for about a year now."
Anna: I have little experience with boyfriends but I have experienced this situation with friends. The case is usually something happened and it has made them rethink about their lives. There are many factors to consider in this problem. One factor would be whether he is avoiding you only or everyone in general. If it's everyone in general, the problem could be bigger than the both of you. You have to talk with more people with this. If it's just you, we move on to finding solutions that you have to fix because he is obviously not going to talk to you any time soon. One, give him time. Very painful method. Or two, talk to him. You guys have been together for a year, you should be comfortable enough to talk to him about this. If he doesn't open up then refer to solution number one. Do not force anything out of him or it would create more damage on your relationship.
