Single Mom Alert

Hi mommies, kind of embarrassed but I think I'm going to be a single mommy. I'm 11 weeks 1 day and me and my baby's father argue over nothing. Its like a entire different person ever since we found out about the baby. He acts like he's happy then the next minute it's fuck the baby, he don't want anything to do with us, he doesn't want to talk until the baby is born. Then he loves me soooo much. He gets so loud and over powering and won't let me talk then apologizes. At this point I just want to be stress free and happy, but I also want the father to not leave me. I just would of never imagined being a single mom. Kind of scared to experience this alone.
