What should I do?

I've been dealing wit dis dude 4 15 months, and I found a letter of his from wen he was incarcerated from a guy telling him dat he miss pleasing him orally so i asked my guy (he live wit me and everything) he lied and tried to say dat it was a girl but aint no girl named Craig! then eventually he confessed to being molested by his big boy cousin wen he was younger, and he was confused 4 a while so he let a boy go down on him a couple of times but he says dat he knows who he is now and who he want to be wit! he claim dat he dont got any friends and the 2 i did meet were gay dat had him on their cell account & bond him out of jail and pay his mom rent. I think dat he is still lying and I feel so betrayed b cause he shoulda told me wen he seen dat we were getting serious. Now im all in love and want to believe him but now im confused I cant even have wit him anymore, I made him leave and move in wit his mom afta running his behind ova I dont know wat to do i still talk to him daily
