what risk do you speak of O-Beller?
The way I look at it: if my baby's father does everything he says he will and behaves correctly then i wouldn't dream of suggesting that he wasn't baby's father. At the moment he is saying he will, but he's a single guy, he might meet someone horrid who doesn't want my child around, etc etc.
I think it's worse to have no father around than one who is a let down and flaky. but I say that from experience. My father was awful but my my mum had to send my brother and I to his house every other weekend and for half of all holidays and we hated it, but if we didn't go he would have got nasty via the courts.
anyway, by not putting his name on certificate i feel i am protecting the baby. But my situation is different to yours as i set out to do this on my own and so have made plans that don't include the father so anythign he does will be a bonus. I feel i'm setting myself up to not be disappointed.
I've actually felt lonely this week. Not pining to be with baby father but just to have a boyfriend to have fun with (not sex particularly, but things like cinema and walks)
