PLEASE HELP!! What can I do to get my mind off of him?

My boyfriend and I are having a lot of issues lately. We just haven't been able to get along and we've been fighting a lot. I swear the last fight was so stupid, but I won't get into all that. What I'm trying to get to is that he wants space and time to figure out what he wants, relationship wise. Which means he might stay or leave me. But he has also been really mean lately. I'm guessing its just cause he's stressed out and all but still. He's never been like this with me before. I'm giving him the space he needs and I'm trying not to text him and just let him be, but how can I focus on other things while I wait for him to make a decision? I feel like this waiting game is gonna kill me. Seriously. I want to talk and fix things NOW but I know that won't help, I need to wait and give him the space and time he needs. Help :(
