Over and over again

I find myself looking at his facebook wall.... Making sure he's still ok. Then i see a post. It says "baby i love u" but its not from me. Its from his best friend.... I am shocked. He told me they would never be more than friends. All the times she stayed the night were nothing. The way she hugged him all the time. Little things. And i shouldn't care... I broke up with him. I keep crying. Trying to make it through the night. That is the worst part. Not dealing with his friends or my friends...but dealing with myself. My own thoughts eat me alive. And then theres him. Yes i moved on too quick. I fall easy. Very easy. So now i can't go back...i have another attatchment. If i didn't have him id run back as fast as i could. God help me and all the thoughts strangling me... Pulling me into a depression i don't wanna fall back into.
