Hi there. Welcome. Well, it's always tough when a pregnancy is unplanned. I think a lot of guys get overwhelmed with the idea of becoming a father especially if they aren't feeling close to the mother.
the bottom line is that he DOES have a right to the child and can take you to court for visitation. and unless there is something major going on like he is a drug addict or you can document physical abuse or things like that, he SHOULD be in the baby's life whether you two are together or getting along or not.
that's the reality. he's the father of this child and your child WILL want to know him. Kids CARE about knowing both parents and it hurts them not to.
BTW, I was married, planned my pregnancies and my husband only went to one ultrasound--- no appointments or anything else. He works and I didn't see any need for him to be there. So, I would not be too upset about this. Hopefully your ex has lots of things going on that make him busy such as a good job!
So, my earnest advice to you is to focus in on the baby. Give him updates without any drama. Don't expect that you two will be a couple as that sounds over but DO make it easy for him to know the baby. You be business like and friendly as it is in the best interest of your child. Having a baby means we have to put our own 'deal' aside and do what is right for the child. You chose this guy to make a kid with (no matter how it happened)--- so, you have to deal with him for the rest of your life. So, make it as undrama like as possible and as businesslike as possible and hopefully it will all work out for everyone.
good luck
I was in a relationship like that for 2 years mentally and physically abused.... I finally decided enough was enough and I never plan on going back. I think you made the right decision. Good luck keep your head up and take care of yourself and your child.
