Its been a year since she left me for our neighbor (long story) after a 6 year relation,I try to move on go out with other girls, focus on my personal achievements etc but even now after a year I can't stop missing her and stop and think that I lost something very special that will never happen again... I though about getting her back but, I simply can't forgive her. I feel there's something missing in me in order to let go, and that's all I want, to let go.

I know this is hard for you but she now has her own life. I know you miss her but there was obviously something wrong with the relationship. Were you doing anything wrong? You may not have been but something was lacking. You are just going to have to try and let her go, you have the rest of your life to live, just one day at a time.

I'm sorry man, I'm really sorry
It takes as long as your with someone to fully get over them
