Sticks and Stones

I've been dealing with this cycle for more than I would like to admit. I should have recognized the signs when we first started dating. Within a week he was cracking jokes about guys commenting onmy Facebook page, but of course, in the beginning of a relationship the jealousy is "cute." That faded. A month after that, he asked for details of my last relationship which remained the topic of conversation for a long period of time. He would accuse me of wanting to get back together with him. He would say that my ex was a better sexual partner, and that I still think about him. We broke up over this a few months in, and he called me saying I deserved better - and I took him back. Then, there was a long period of good times with no fighting. Now that I think about it, he didn't have a job and he had no money. I was supporting him ... financially and emotionally. He was going through problems with his baby's mother and visitation. She wouldn't let him see the child. I comforted him through all of this. Of course, he says his baby mother is crazy. It seems like he always has bad days and when I have them I am told to "get over it" and "stop causing drama." He wasn't working so paid for everything, going out, etc. and even gave him money to live on a daily basis. Maybe he was just being nice to me because he needed me then. It's really sad because I have a good heart. And I thought things were turning around then because he realized he didn't want to lose me. I am so naive. He smokes so much pot. I tell him maybe if he stopped he wouldn't be so paranoid all the time and abusive. He tells me to stop nagging him all the time. I sit here alone and I wonder how I can be a successful business woman who makes big decisions for my clients, but I can't help myself. I'm so mad at myself!!!! Why am I so stupid??
