Made a stupid bet with a friend and boyfriend broke up with me?

Okay so basically me and my friend made this bet on to if I reach a certain amount of followers on Instagram. He would give me money. My friend suggested that I should follow people so that they could follow me back. So I did that. My (ex) boyfriend had my account and saw I was following a bunch of people. And he got mad I unfollowed them without him even asking. I agreed to the bet because I wanted the money, to buy my (ex) boyfriend our monthsary gift. I don't know what to do I’ve explained to him the story with proof and he even had my account so he knew I wasn’t cheating or messaging any of the people I’ve followed. He’s basically saying it’s my fault. I feel bad and I don't know what to do bc it feels like his overreacting and his not talking to me/blocked me everywhere and avoiding me in school.

And his being petty posting stuff on his Instagram, like how he’s like moved on. Basically posted and the caption was “hoe hopping” and a bunch of girls were tagged in his post-😐
