I have the same case as you, my due date is May 2013. Baby's dad is my age 23 years old. He broke up with me. He told me he can't handle this, he scared the baby gonna ruin his life and he worried he can't afford of having a baby in his life right now. Few weeks ago, we constantly fight over the small stuff. But he likes hanging out with friends and want to have his "freedom". I am still depressed about that. I'm so worried to be a single mom without him support me in every ways as way.
But I figured I can't force him to be a dad when he is not ready, so I think I should just give him some alone time. It's so heart broken but I would never give up on him, I just want him to come back to me for time being. I hope he realize how much I love him, how much I want him to accept the baby and I in his life, I wouldn't want because of the small matter we end our relationship. I'm still so worried about it.I even cry everyday and night about it.
So my advice is be strong and give him some time, let him realize how important you and the baby are for him. If you guys are meant to be with each other he would come back to you eventually. Be strong!!
