I agree that I don't think he would have sex if he didn't have some feelings. There has to be some old feelings there. However if he has moved on then this sex was just an afterthought. You need to keep in the back of your mind that he still has feelings but that you have damaged the relationship and he may not be able to accept the cheating. You can't put your life on hold for him. You can return to college and try to start to move past this incident. You have a wonderful time in your life and you should behave as if single. That way you aren't waiting for him. If it happens great if it doesn't fine. you have to accept that he may not take you back. Either way you have to be okay.
If this has been helpful press accept
Yes he would. He seems to be asking for just a break. He could change his mind. Especially since he seems to be unsure. You are going to have to have a lot of patience because I think he is going to take awhile to sort this out.
Be back later
If you had a long term relationship it is likely that he has feelings deep down and has strong feelings. The question is what he wants to do about that
