What should I do if my husband keeps leaving the house?

I've been married for five years, but everytime we have a fight, my husband leaves the house, some times for a couple of days, sometimes for a whole week. He disconnects his cell phone and plays hard to get. This has happened for about twenty times now. I'm tired. This time I didn't ask him to come back. Now he is desperate, he wants to return but I don't want him to. Because I'm tired. I don't know what I feel anymore, I'm confused and I feel humilliated. He doesn't want a divorce, but I don't want him back. What should I do?
