Pregnant but can’t leave

My boyfriend is getting station across the country in a few months and I just found out I’m pregnant. The biggest problem is that I have a child from a previous relationship and her dad is here so I don’t think he will make it easy for me to leave with her. I have no idea what to do. My boyfriend doesn’t think this is the right time to have a baby and I agree, but I don’t think I can go through with an abortion. But I also think I’m being selfish if I decide to bring a baby into the world that won’t have their dad there for most of the beginning of their life. I’m so conflicted, this is the worst feeling and decision ever.

Has anyone ever gone through anything like this??
