Do I still have a chance at winning him back or should I just try and be good friends with him?
I actually think you should respect his wishes and leave him be. And by that I mean absolutely no contact with him. Nuclear option. Delete and block.
I'm not going to try to interpret his actions because... why? He broke up with you. What he was thinking doesn't matter. You're not responsible for his emotions or his behavior. This is what he wanted, so respect that and give it to him.
And I don't suggest this as some kind of a punishment to him. Rather, it's for you to heal. If you try to be "friends" with him, you'll always hope and wonder if maybe there's a chance of getting back together. And then when the day comes that he meets someone else, you may end up being hurt, and then HE'LL be confused because, after all, you guys were just friends.
If after a period of time the hurt wears off and you want to actually be friends with him, go for it, but not this soon. It seems to hardly ever work out and there's always one party who gets hurt.
