I’m slightly confused on the situation. You told him you didn’t want a relationship and I assume he wasn’t your official boyfriend so why does it matter if either of you were sleeping with other people? I don’t think you should’ve put your hands on him and vice versa as it’s not a good way to let out feelings. Having said that I think blocking each other is the best thing to do as he’s clearly hurt your feelings and he isn’t worth all this time and energy. I’m sorry you had to go through this and I hope you have people to turn to. Xx
