Birth certificate..

Could someone give me some advice.. I'm 8 weeks 4 days and I split up with my boyfriend 2 weeks ago due to him becoming very controlling and possessive.. He wouldn't even let me get my hair cut! I'm not wanting to put him on the birth certificate due to him turning nasty and threatening me. I've recently found out the true colours of himself and his family. I've had to get the police involved and they've had to flag my house as his family are very dangerous people. My ex smoked weed. He promised me he'd give up but he never has and his dad is a drug dealer and smokes it too! Honestly at first the weed didn't bother me but now an innocent baby is involved it did start to bother me as he was more interested in the drugs than he was with me and the pregnancy. He's more interested in spending money on himself than saving for this little one.. What I'm trying to get at is has anyone gone through this or is anyone in the same boat as me? Can he take me to court and force me to put his name on the birth certificate? And can he force me to make his family see this baby? As all they've done is given me trouble. I'm going to be doing it through a visiting centre when the baby is born so I'm guessing the visit will be supervised. Thankyou to whoever can give me advice.
