I need advice!!

okay so I've been talking to this guy and he makes me so happy he's someone I really can picture myself with. Hes turning 22 I'm 25. I'm not one to really care about age either (to an extent) so anyways he recently told me that while he was out at the bar with friends ( I thought they were guys) they were actually girls anyways one of them got really drunk and she grabbed him and kissed him he says he pushed her away.. but I mean why did he have to wait weeks to tell me. I'm feeling confused on what to do. I really do care so much about him but I feel hurt in a way I know were just talking not dating yet but I mean I want that respect.

Update: Thank you ladies I took the advice and we talked. He said he's sorry and feels bad about what happened. also we talked and decided to take it slow and build a strong relationship. i hope it will all work out and we can have that in the future you know. Thank you ladies for the advice!!! 🙂
