I’m in the same position, and decided to keep the baby after lots of fertility issues years ago and mmc’s. Straight after I told the father he blocked me, would rather not be part of the babies life, and pretend that this never happened. In his eyes I’ve had an abortion or lost the baby.
I won’t lie, some days it’s tough, I wonder how I will cope, sleepless nights, later stages of pregnancy on my own. A world of thoughts spin round my head. But I KNOW I have made the right decision, I would rather do this alone, and give me and my baby the best life without someone dipping in and out as they please, offering half arsed support, and I’m not having to co parent with someone who is an idiot! I have realised that the emotional and mental support that I need, he is never going to provide. But I have had so much help from my midwife, friends, family, neighbours.
OP you can do this, leave him be, he has made his mind up, you need to focus on you and the baby. I told him that he has to respect my decision not to have an abortion, and live with the decision that he has made. I might be stupid but I’m not going to claim CM, I just going to do it alone. Hopefully one day we will both meet people, who deserve to be in our lives. Good luck, hope the morning sickness gets better xx
