I can’t take this break

Things have been rocky for a few weeks, maybe it’s been a month. He’s in another city right now visit family. We fought before he left, we’ve fought over the phone while he’s away. I’ve been feeling so insecure about our relationship and whether he still wants to be with me. I’m not handling the time apart well. After a long fight, we sort of agreed to shut of communication until he gets back. I don’t know if that was the right thing to do. I’m just really hurting right now. I don’t know how to have faith that it’s not all over, but I’m afraid to hope for that. Has anyone had a break and come through it better? Is the end imminent? How do I treat the break so it’s not a waste of time feeling sorry for myself?
