leaving my boyfriend

I'm leaving my boyfriend. I'm going back home to Arizona and I'm taking the baby I feel selfish but we can work out something to where he can see him once a month. He keeps telling me we can work in things but I'm tired of working on things that never get worked on. My whole pregnancy was nothing but fighting I was never happy, and I'm still not happy. I feel bad taking the baby away from his family because it's his moms first grandchild and his brothers first nephew, they've done so much for and been there for me more than he is and I feel really bad, but I just want to be happy and enjoy my baby without any worries.
