i gave the above answer 1 thumb up.  i'd give 2 but it was a bit harsh, tho' i agree that sometimes tough love is best.

sonya, a very long time ago, i, too, had an affair with a married man.  i can tell you this from experience:  married men NEVER leave their wives for their mistresses. 

and i think he showed that to you by choosing to make "space" for himself.

it's not hard to forget someone you've loved, married or not.  but in order to have someone love YOU completely (he couldn't love you completely while having a wife), you must love and RESPECT yourself.  never waste your time on a married man again.
