The situation is as follows: the relationship lasted roughly 2 years, I decided to call it quits because I was severely lacking attention (and by that I mean being stood up on, sporadic texts exclusively late at night, after the day's work is done, not a single invitation to a date for more than a year, etc). I wanted to remain friends and expressed it; my ex admitted to my complaints being fair enough, but claimed to still love me (in his own internalized way). He hasn't contacted me for weeks, although I clearly left the door open. Guys, what are the real reasons of not contacting your ex after a break up? Please help me figure this out.
