This weekend sucked so bad. A month ago I started a poly relationship with a married couple and everything was going amazing until Saturday night. We went out and when we got back, the husband cooked a great dinner and we were just hanging out and talking. The husband's brother lives with them and came into the kitchen. We moved out of his way but he still made it a point to purposely step all over me (literally) and back into me pretty hard. Just to be a jerk. The husband started hollering at him and I was trying to stay calm and breathe. I have a lot of trauma and I was very triggered. After that happens, his wife starts bringing up sensitive topics in the relationship that should have waited for another time. I made it known I was overwhelmed and needed to breathe. 
I go outside and the husband joins shortly after. He is really grounding me and helping me and the wife is pissed. Going in and out, just glaring at us. Then goes out to her car and starts throwing a fit hitting the windows and everything. Then starts an argument with her husband and gaslights the fuck out of him. I reached my point and said I need to leave. So the husband walks me to my car and we talk. The wife won't leave me alone, walked to my car, knowing how upset I am. Trying to force me to look at her while she's talking. I really maintained myself even though it took every fiber of my being. I tried so hard not to embarrass myself.. I finally go home. The next day, she turned her husband against me by manipulating a conversation we had together. The conversation was about sex. They apparently agreed to no sex but did not communicate that to me, but the husband was talking about us having sex together that morning before right before I came over. I told her that I'm glad that it was cleared up before it happened. And that I normally don't have sex during that time of the month anyways, so it's not a big deal. She fucking told her husband that I said he pressured me into agreeing to sex while on my cycle. I did not say that at all!  I truly loved him and feel like I lost a huge part of my heart. She is a puppet master and I fucking hate her. After she lied on me, and now he said he doesn't feel "safe" around me. He wouldn't even give me a chance to explain my side, he automatically believed her. 
I feel like she took advantage of that horrible night and twisted that conversation to benefit her. It kills me. Earlier that day she was telling me how she wished her husband treated her the way he treats me. She was mad because her partner (boyfriend)  was also there on the date and he called me beautiful multiple times, called me sweet, and nice. I think that it pushed her over the edge. She knows I have bpd and that night she kept pushing me, and I think she did it purposely. Now she is having people from her home state stalk my Facebook, to the point I just deleted it. I am hurting so bad and I feel like I lost my soulmate. I want the absolute worst to happen to her, the rage I feel is unreal. The abandonment I'm feeling is undescribable.. sorry for the long post, I just have to vent..
