Ill try and cut a long story short. I was with my ex for approx 3 months before i found out he was chetaing on me by messaging other girls ect, found out i was pregnant end of November 2020, we tried to make a go of it again but he was messaging other girls again. Mid January he turned around to me and said he wasnt sure he wanted to be in babies life or ready to be a dad again(he has an almost 2 y/o from previous relationship who he sees 1 day a week but doesnt really watch his mother does it all. He didnt know what food to give her or what clothes size or shoes size ect. He doesnt know how to put her down to sleep as his mother does everything) . He really suffers from mental health issues and has attempted suicide twice since ive known him. When we broke up he was very manipulative to me telling me he was going to go and commit and it would be 'our little secret'. he refused to get help from the doctors and said he would deal with alone when i said i wanted proof he had tried to get better. He recently messgaed me saying hes still not ready to be a dad again, but will be in a month(how, how can he know that) and saying "its a good thing were not talking as im going to go off the rails soon" . Basically im worried hes going to be in and out of babies life and could almost cause more harm than good. Him and his mother never stick to his daughters routine or anything when shes there and I dont want to mess up this babies routine once they arrive.
Will i be taken to court or anything if i dont put him on birth certificate or let him have access to the baby. He is a very manipulative person and compulsive liar and believe he wouldnt watch the baby it would be his mother. I really want to breastfeed and he wouldnt be happy if i said he couldnt take baby away from my home.
