So my baby's dad hasn't wanted my baby since I announced my pregnancy. It got to the point where he made me really ill throughout it with stress from his verbal abuse.. he made my life really unpleasant, since having baby he's somewhat changed, he isstill a bit disinterested but hasn't been as verbally abusive... his mother however is over the top and very pushy, she's acting like my child is her own and like everything I'm doing is wrong.. she's guilt tripping me for living apart from my baby's dad (his choice) and telling me everything he's going to miss out on and that's my fault... they are unpleasant people, and I don't want them around me or my son or have anything to do with us.. how do I legally go about this? He's on the birth certificate
