Leave now or after my exams?

I don't think I can deal with the stress of a break up now but I would feel its mean waiting till after my exams to break up with my boyfriend. Obviously I'm worried he will change, he even said it himself won't you be upset if I change for the next girl. I will but Its gone on for too long 4 months, I have told him multiple times I'm not happy and he hasn't treated me better. I don't have time to be a crying mess after a break up but I also don't have time to be in my current uncertain upset state of mind. Should I leave now or after my exams? Our relationship is in Limbo at the moment and has been as of Wednesday.

I left his place on Wednesday morning It's now Friday. My exams are not this Saturday (tomorrow) they are next Saturday and the following Monday.
