Is he consider cheating?

If he's not cheating yet, he wants to be.

You guys were on a break right? But if you planned to get back together and he did that I wouldn't exactly call it cheating- but to me it would be wrong, I would feel hurt if I were you especially if your back with him? To me breaks seem like you're still together it seems like you just don't see each other or talk to each other for a while so that would be wrong of him to do that while on that break.

If you guys were never exclusive than it's not. If you don't want him to be with anyone else you have to be exclusive and let him know that is what you want.

If you had a break for 2 months he was free to see whomever he wants, maybe he did that stuff before you got back together and is not even considering cheating.

I had the same thing happen to me. Any man who does this is either suffering from an inflated ego, or playing with multiple women. Don't fall for it. Tell him he's not good enough for you. Good luck
