First, congratulations! I'm happy to hear that you know you and your daughter will be fine. I'm sorry to hear that for what ever reason, you will be raising her without the help from the father. It sounds like it's out of your hands. You can't make someone be a dad if they don't want to be. Please believe me when I say it will be his loss!
The pain is just going to take time. Right now you are pregnant, emotions may be a little out of wack and you might even have too much time on your hands. Wait until that baby is born, you'll be so busy and so in love with that baby that your world will feel much better than it does right now.
I'm always around here if you need or want to talk.
