maybe you just want the idea of having a good relationship that you obviously didn't have with your ex,he was a part of your life for 2 years so is gonna be in your thoughts and you wish for the perfect partner that you wish he was but wasn't,there is good guys out there and he will come along for you when you least expect it,remember how he was and what a ar$e he was and know that things can only get better and pity the poor s0d who gets him next,don't let him get to you,hold your head up and move on,it may be hard but it WILL happen!!
