Am I thinking too much?

So the guy I’m seeing, yes he finally made it official admitted too “cuddling” this chick early on when he was living with her WHILE we were first dating. Well he said he removed her everything. Then somehow she comes up last night. I didn’t say anything at all just pushed it too the side cuz I had some shit that I was doing on my car. Then I act like I don’t see it and he starts laughing and says “oh frank”. Like what!?!? I clearly seen it said Shyann not Frank. So why lie? Am I over thinking it?????

Update::::

He keeps avoiding it. I’ve tried talking to him about it but he won’t listen. I’m done honestly. I’m better than this.

He changed the password too his phone and took my finger print out of it so that’s obviously another sign
