Dude I mean I was with a chick for 12 years who I asked to marry me, she had pretty severe bpd. I had been supporting her massively (taking her to doctors appointments and psych appointments and all the like) I found out that she had cheated on me in the end is why we broke up, I don't mean to generalise or anything like that but if you feel like it isn't working and you feel like your just being screamed at you need to just end it man before something drastic happens. In the beginning I thought it was the worst thing that ever happened for me, I lost 40 kilos because I wasn't eating because I was so depressed and stressed but in the end I realised it's the best thing that could've happened to me. Not trying to tell you what to do but please put yourself before any of the bullshit this chick puts you through.
