33weeks /Mentally going wrong / infedelity

I believe I’m loosing my mind . I am 33weeks pregnant about a month ago my partner had confessed he had genital warts/HPV he got from paying a prostitute back on July 30th. When I found out I cut all contact went on a alone time since Sept20th he confessed.

I was stuck at home depressed crying and not eating . I just imagine what he was doing to her . Yesterday I got on a angry rage attitude just knowing his family knew and went to his job the car that he has driving is a car I had got him 2 years ago I scratched it up and broke the rear mirror . Before he cheated I had bought him a brand new iPhone I asked for everything back I know petty but he took out his SIM card and restarted the phone and gave to me .. but I was lost in my head/anger . We are going through a process of papers being filled out due to the car so I signed some he tried to hug me and say he’s missed me and he loves me and I just started hitting him back to back crying how could he do this to us . To me. I feel I am lost my head because I told him it was a goodbye and he kissed me and as crazy as it seems I asked him to have sex with me one more time . So he said he will but with condom so we had sex on the back of the car all I wanted to think about is the way he would fuck the prostitute . I didn’t feel no love no nothing I was just so messed up in my head he was done I got up and he tried hugging me saying he loves me and I just took off. Without saying a word . I feel like I lost my mind pregnant alone and got cheated on. The love isn’t there in me it’s like hate and sadness that I need to be on my own for a long time .
