he wants me back

Honestly, I don't know what's the actual reason we broke up besides the fact that I'm tired of all the tiny fights we have, we are very fragile but we don't break. And only just few days ago, I said I'm not going back to him. But he kept calling me and tell me he loves me... I know he does and I do too. He's never cheated on me, or do anything that is terrible, besides the fact that he can be quite unreasonable and he can be a dick sometimes. But in the end, no ones perfect. I don't know what to do. My heart says don't give up, my brain says give up. I think I really really want a big break and maybe get back together. But at the same time im scared we won't get back together and that I won't find anyone else ......
