Hi I’m 26 (M) and my partner is (27) female. My partner and I have been together since we were teenagers. We’ve spent most of our 20s dealing with mental health and just recently (past year or 2 ) started to understand her BPD amongst other things. We were doing well until Covid hit. And then she graduated from school and was home from December to March in which she spiraled even further, almost costing me my degree because she leaned on me heavy for emotional support to the point to where I could not even attend my classes or do my homework because she wanted 24/7 care. She got a job in March which allowed me the room I needed to finish my studies barely passing. After I finished my studies we learned her aunt passed away which sent her down another spiral understandably. She has mostly recovered from that( I don’t think you ever fully do but she was doing better) but now we are trying to move into a place that is nicer than the dump we live in. Almost immediately after signing the papers she started sleeping over at peoples houses for weeks on end. We both work at he same place and she has been sleeping over at a guys house majority of the time. She says he’s to young for her and that nothing would ever happen she sees him as a little brother but something just doesn’t feel right. She’s sworn up and down nothing has happened or will ever happen. Yet she talks about him all the time, she gets upset with me over little things. We  finall had a sit down talk and she swore she has never done anything and would never do anything. But her word is pretty flimsy. I’ve caught her in a lie many times when it comes to guys. And promiscuity is high on the list for BPD people. At work today someone said that said guy she’s been spending the night with comes to work now with a bunch of hickies pretty often. I know he was trying to date a different girl but my attenenas are up and I’m having a hard time trusting her. Especially when she just comes home whenever she feels like it. Honestly my love for her is fading because I feel so disrespected often. But she says it’s not her she says she’s just going through something and she needs time but she doesn’t really want to do anything about it. Meanwhile I’m left to take care of the cats, clean and pack on my own while she goes to the lake, movies etc with other people coming home occasionally and leaving a mess when she does. I’m at my wits end with her and idk how to feel. In a normal relationship all of this would be bets off. But I know it’s a BPD thing, but I can’t help but to feel some resentment. A lot of resentment. She doesn’t want people to know we are together at work so she lies and says she’s single so people go around thinking she’s screwing this guy she spends the night with all the time and I have to hear about it. I feel used and like I’m going mental and she feels nothing. What do I do? Thinking of joining a boxing class or something to get rid of all of this anger I feel. I’m really trying to be understanding. But I can’t help but think I would not accept this kind of behavior from literally anyone else. BPD or not. But I’m dating her and have been so I’m trying to figure out from other BPD people are care taker of what I should do or how I should feel. Cause right now I feel really disrespected and resentful.
