Rant #2054

Hey so me and my now ex was together for only a month and about 2 weeks in “WHICH HE SHOULD ATILL BE IM HIS HONEYMOON FAZE) he switched up completely like dry avoiding calling everything so I tried talking to him many many time trnna find out what was wrong the this girl added me and he text me right after saying “don’t add the girl she’s trying to cause trouble she’s going to try use my past against me” and I believed it and I promised and then another week goes by and it just gets worse so I add the girl bc my gut was going off and she said the day after I said yes to him asking me out he text her saying he wanted to do sexual things to her while she was drunk and they also made out and I was shocked so I confronted him straight up and he said “ how dare you break a promise I told you not to add her fuck you were done” like how is this my fault and before I can say anything he blocked me on everything he even blocked my best friend and I just feel so betrayed and hurt and angry
