What is the difference if I don't name ex-p on my baby's birth cert? He has been awful and I think its not a bad thing if he disappears and lets me get on with things....he won't be consistent and will breeze in and out as he feels....in the long term I think he will do more harm than good. Can I do all of this? I just want my baby to not grow up completely confused and thinking its dad is unreliable....
