Is this a normal reaction?
So before covid kicked off I was dating this guy, he's 24, I'm 20, we both attend university together. In Feb he went out on a night out, but I stayed in because I had an essay due, anyway the next morning he came over really upset. He broke down and told me he'd cheated on me the previous night. To which I told him that's fine because we'd only been together since December and hadn't actually talked about whether we are exclusive or not. To this he kicked off majorly, started shouting at me, accusing me of cheating and ranted on about how I didn't love him. Which of course I didn't, I maybe young but I'm not a naive school girl that thinks love develops overnight, it'd been 3 months and a month of that we were both apart anyway.
Anyway, so he broke up with me for not being mad at him for cheating on me essentially. Which was fine, I figured he was just looking for an excuse and was hoping to take the cowards way out and get me to be the dumper. But then a month later he sent me a text asking if we could meet at Costa, which was fine, we met it was nice and then we were talking and he said, and I quote "I've done a lot of thinking and I'm ready to forgive you" I nearly choked on my drink. He's forgiving me! I don't actually understand what I did wrong here other then not being mad at him for sleeping with someone else.
Was his reaction to my lack of reaction normal?
Am I the one in the wrong for not being angry at him? Obviously he's a scumbag dont worry he's been blocked but I'm still confused about the whole situation. Advice please.
