lost

Ended a 6 year relationship today. have been reading a lot for the past couple years. chose to stay, i guess i wanted to make sure, because i was with him. for 5 years we were long distance, thought being together everyday he would change. i have been home for a week and he has cheated, lied and stopped calling. amazing.
sometimes i feel stupid for staying. I knew, so why am i so upset? before i came home i had decided not to stay with him. i am tired, exhausted. want my life back. I know what i should be doing but right now I am lost. I was hoping to share and maybe feel some relief. Can't talk to family, they would not understand, he charmed them too. he is also an addict. witch i said i would never be involved with. Helps him cover his feelings and I feel makes it worse. There are a million stories to share, but Here for me not him.i want to move forward, not in the past, thank you
