Tired

Why do I keep letting myself be used? Why do I put up with all his bullshit? He takes their calls when he's hanging out at my house...goes outside with a big grin on his face when they call. Thinks its funny that it bothers me. I fucking hate it. I don't like being treated like dirt. I hate that he came over to have sex with me yesterday and then is out there talking to her today. It hurts so bad. I just don't even know what to do anymore. I'm on round four and its not getting any better. Round one was all insults...round two was losing money, getting shoved around, insults and pregnancy...round three was getting punched, getting in a car accident, insults, money and heartache...what the hell could possibly happen now in round four? Will I survive it?
