When is it time to call it quits????

I've been seeing this guy for a about a month now and I'm starting to get that itch. I don't know why I get this itch so early The average person gets this itch after the first 6 months, not the first six weeks. Is there something wrong with me? It's like I have the relationship attention span of a man. I get bored, irritated, and frustrated. I think in the past week I've broken up with him three times. Over the phone... And in a text. as fucked up as I've been I might as well have broken up with him on a post-it! A POST-IT!!!! I would have never thought I'd be this girl. I want to be able to be satisfied in a relationship. I want to be able to be calm and content with a comfortable routine. But right now that's not me. And I'm guessing, to be able to have all those things and feel content I have to do a lot of work on myself. Fix my mind. Make sure I know what I'm doing before I go messing with a another mans spirit, because I know I've taken the spirit and smile from a man. I just need to stop...
