Should I take him back after he is over his ex?

I was dating this guy and we have a lot in common and we get along very well but he kept going back and forth in our relationship. We dated for like 2 weeks and he tried breaking up like 3 times. He was indecisive about dating me. Turns out he isn't 100 percent over his ex. He claims he loves me but he needs time to move on. Should I take him back after he is 100 percent over her?
