Kenna,
I'm kind of in the same situation. Me and my ex lived together and then broke up, but I couldnt afford to move out right away. I ended leaving about a month after the B-Up, but as she grew distant in that time, I became enamored again.
When it came time to move I was devastated. Like at first I was ready and excited for the fresh start, but then the time until the move allowed emotions to percolate and rekindle old flame. For me not her.
I guess I'm saying becareful not to fall for him if he's completely through with it.
