Great New and Bad News

I had my first u/s today and the baby was really moving around and I got to hear the heartbeat! I almost cried because now I know it's all so real.
On the other hand, I broke up with the father before I found out and he wasn't accepting of my decision not to abort it, but when I asked if he wanted to see the ultrasound photo he tried to claim it wasn't even his baby. He, I and everyone else know that's not true, but he just got to be an annoyance like always and I had to block him because it's too much stress.
I'm not asking for him to be in the baby's life, all I want is for him to be civil when I do have to talk to him. I don't know what to do.
