Most people consider it emotional cheating, and I do as well.

Another issue is that you MAY have only been setting with the person.... but, how do I know that’s all you did? Maybe you’re meeting up with them and cheating on me physically as well. Either way, you were probably sitting in the same room as me and talking about what you physically wanted to do with some other person instead of me and... gross. Fuck that. It all just falls into the same category for me: you’ve made me feel that you can’t be trusted to be faithful and that is a dealbreaker.

I have NO issue with porn. It’s adult entertainment. If I put a limit on his porn, I may as well be expecting him to assume I’m cheating with my vibrator.
