How can i break up with him my co worker without hurting myself?

Same thing seems to happen to me everytime and I thought I was the only one in this world that had bad luck with men lol but hey if he's such a jerk then dump him straight up. I think it's the fact that we give these men to much of an easy pass and we are too nice. Don't feel bad for that loser. Good luck babe one day you'll find the man that's right for you.
