I have had a difficult time moving past a short relationship. I know the man is no good, but how come I feel like I can't let him go? There's been countless red flags and my girlfriends all think I put up with his crap too long. He recently took a job in a different state without telling me until he was already there. He returns every two weekends. He says he misses me and wants to see me, but I am afraid that seeing him will set me back emotionally. How do I tell him it's not worth it?
