What do I do about this situation?

After a argument my boyfriend of 3 years said it was his breaking point with me because I wouldn't kiss him back. He told me he needed time to himself to think about what he wanted in his life and when I asked if we are breaking up he said he didn't know yet. Do I just wait on him? Do I assume we are over with even though he said he didn't know yet?

If he does come back how do I deal with the hurt this has caused?

It has been 5 days since we've talked i told him i respect his space and that I would leave him alone for a while. But I don't know when I should talk to him again.

Just also have to add that we live together and he works out of town which is what has been putting a strain on our relationship.
