What does it mean if my boyfriend told me he wants to "start over" as friends, and work on our relationship.

My boyfriend broke up with me yesterday, because we argue too much. However, I feel as if I can't do anything right, no matter what I try, and I really have no idea as to how the arguments start or why they happen. He now says he wants to start over as friends, work on our relationship, to hopefully start dating again. He said he doesn't want to see other people, and he doesn't want me to see other people. I do not want to be broken up, nor stay broken up. Does anyone have any advice for me, or pointers in what I should say or do?
