what to do?

I finally put an end to my relationship its been 2 days we haven't talked. There still some stuff of his in my car, but i told him i was changing my number if i text him his gonna say some shit like I didn't have balls to change it. But if keep it here his gonna have something to come back to something to hold on. I am not willing to go drop at his house again. I was there and he only took half of it. What should I do?
