I haven't heard from my baby's father in three days or so. I'm honestly so emotionally hurt by him it's ridiculous. I don't want to care what he does, but when he's the one who wanted a kid and all that, I would think he would be checking on us every once in a while. I don't feel important to him anymore. He says he's just trying to get his life together before the baby gets here, but is out partying all the time...It's hard to even believe him. He says he wants to get back with me, but he needs to work on himself first...yet I'm seeing no progress and I honestly can't wait around. I'm just tired of feeling worthless to him. I love and care for him so much but ask he does is hurt me and I'm not sure how much more I can take.
