Sorry, but I agree with the others that he does have a right to be there. Having a child isn't just YOUR experience, it's his experience too, as is the whole raising of the child. Saying that it's his right to be there is true, and it has nothing to do with male domination. Many years ago men weren't allowed into the delivery room, or even to stay at the hospital, because birth was considered to be 'women's business. Then again, in that same period, so was the raising of the children. The men worked, the women stayed home, and there was no choice in the matter. My Grandad wasn't even allowed to stay at the hospital for my Dad's birth, he was just sent out into a winter London night and told to come back the next day!
I think that you obviously had a difficult and complicated birth the first time around, and that you have a lot of misplaced blame and anger at your partner. I really think you need to try and talk calmly and carefully to him, and explain to him how he made you feel the first time around. Explain to him all of the things that you don't like - but I firmly believe he certainly has the right to be present for all aspects of the child's life, just as he was for the conception of your new bundle of joy.
I also believe that parenting is a partnership, I don't make all the decisions just because I'm the Mum, we share the joy and the responsbility of our children, and I view that as an increase in both men and women's rights that our relationship works in this way. My partner and I both have an amazing bond with our son, and I think it's because, in large part, we share ALL of the duties of parenting. I love my son dearly but we aren't just mother and son, we're family, and having him there for Lucas' birth, and for the birth of this child reinforces that view.
