Cheat

Me and my x were working together in the same hospital we started dating each other we fell in love than after some time I started doubting him that he’s hiding somthing and I asked him then he told me the truth that yes I am in a realtionship with a girl from past 8 years but don’t worry I will marry you for sure he somehow conceived me and I took a decision to be with him but after 8 months he said the girl parents are very strict and putting pressure on me to marry her bcz they knew about our relationship I cried then again he assaured that he won’t leave me at all he will marry me and he got married to that girl, but it was a long distance marriage so they lived apart from 2 years in between this time we were together and spend every single day with each other we were in a physical realtionship… After some time I fell sick and started feeling serve anxiety and emptyness but he used to always gaslight things … he was also physically mentally i emotionally there … he took care of me but every time I talked about divorce with his wife he used to say that it took reasources and money divorce isn’t easy thing … Because of all this I fell into depression and diagnosed with bpd and started taking treatment and he started behaving a bit cold … Then I told his family and his wife and they somehow judged my character and his mom said to me why did not you came before his marriage to talk to us …. And they put all the blames on me the guy said that she’s not mentally stable what can I do in this case
