We were supposed to get married in two weeks but my fiancè called it off and I've been crying. I also had a miscarriage three weeks ago so I just feel worse. We have been together for six years. He called it off because he found out two years ago I had drinks with his ex-wife. Me and him were going through some things. I thought we wouldn't be ok. I saw her at the bar and started talking to her and asked her about her side of something. There was something that happened between them when they separated. It ruined any chance of them getting back together and I've always heard his side of that. And because of what I was told, my mind went to "Ok we hate her." I understand that at the end of the day I was in a long term relationship with him and talking to his ex about a very painful situation was not the right way to go. She did say she's happy someone finally will listen to her because he turned all her friends against her with that. She just wanted to be heard. I listened, however, her side was almost identical to his with one difference. And honestly that difference doesn't really change the context for me so after hearing her side I can confidently say "Yeah my fiancè was right." I know this is confusing since I'm being vague but it's also kind of disturbing how she thinks that one part whether true or not really changes anything. Yeah she was wrong. But we just continued to have drinks. How he found out is her sister had messaged him on Facebook with a picture of me and his ex wife because we were drunk together saying something disgusting like maybe we can have a three-way. He asked me. I lied. Then finally told the truth and he was really upset with me and asked why I would do that. The whole night ended in tears and he told me I was awful for doing that and he trusted me. He started having a panic attack and when I tried to console him he pushed me off of him and told me to leave him the fuck alone. He said I had lied to him and crossed such a bad boundary. He called off the wedding and is needing his space. I'm giving it to him because I had never seen him cry like that or have a panic attack like that. I feel like a shit person. Idk what to tell our friends and family and all I can think to do is give him space.
