You are go uptight. Unwind, relax and quit worrying about chit you have no control over. Forget the ex he's your ex for a reason. Make yourself a friend that don't know you or him and start having your own life. Persue your own happiness avoid the drama crowd and cry babies, open up, flash the boobies play some pool, join a bowling league. Do things that get you out in the social world.
try to let him go he was not for you its jus sex for him
You will find many of such incidents here. So, reading about others situations, will make you feel 'you are not alone'. Believe me, with time, you will be able to overcome. Give yourself good time and some treat as well, as you came out successfully out of a stressful relationship.
I completely understand your situation. tell yourself 'time will change' and hold on to your goodness .. I was there once upon a time. It wont take 5 years..
