Am I the bad guy in this?

Basically I split on him badly because he was displaying certain behaviours which I didn’t say anything about but was offended by. For example one of these situations occurred after I stayed the night. He said he had somewhere to be so I had to leave and I was waiting outside for my cab for an hour and he never left his house. He text me something but deleted it. From there the connection I had towards him started to dwindle and I found myself getting resentful. He travels a lot so he’s barely ever here. But last time we slept together was last month and I was certain he was seeing other girls which made me jealous and I don’t know why because the last time we had sex it was crap cos there was no connection at all. He came and I didn’t. Then radio silence until Monday I finally had enough after I slept with another man and the sex was so much better. I got drunk and text him saying I knew he wasn’t really that interested in me and that we was shit in bed 😅 and that I was going to delete his number cos I found him boring. He’s reply was “That’s ok 🙃” after that I guess he wasn’t really taking it that well cos after not watching my instagram story for weeks he was watching everything I posted the whole day. Before he unfollowed me on instagram 😂😅

I know it’s far fetched. But what do y’all think the chances are of him coming back? Cos now I have to hold it because I’m too stubborn to apologise.

Part of me feels pure evil but there’s also another part of me that feels satisfied because the way he was making me feel.

Thoughts?
