I've tried, but the interest level just goes waaaaay down and i eventually lose contact through a lack of interest. None of my breakups were nasty.......but you just move on i guess.
It depends on the sitution surrounding her/him getting back in ur life. If he/she is pursuing you, sex it up! Sex with an ex after time apart is usually (in my experience) unbelievable and typically much better and wilder than when you were together.
But for some it's hard on their morals to look a girl that u liked in the eyes to know she's just a lil hoe. For others it's EZ and ass is just ass....i guess im in between although id like to say im on the ass is ass side but that always seems to shift when im put in a situation like this....guess its kinda like a turn-off!!!
