restraining order...

So very long story short... my husband and I have been married for 2 years and have a 14 month old and just found out we we're pregnant again in the beginning of June. Our relationship has never been great and he has a history of violence and a mood swings disorder.. well sometime in June a couple weeks after we found out we were expecting we went to a friend's house and my husband drank and we got into a fight and he got violent to the point were he choked me untill I passed out and woke up to him poking me saying "oh I didn't kill you" his mom came and got him after he called her (like always) and he spent the night there and said he was done with our relationship so I went to my family's in Florida, a week later we decided we would try and work it out.... Well a month after that in the middle of July it happened again and again he threatened to kill me and I got him on recording admitting he beat me while pregnant and him saying he wanted me and the baby I was pregnant with to die because he never wanted him and then he left, he's been gone since but only we only talked when he wanted our child which I thought I legally had to let him see him. other than coming in the house when he pleased and taking things that belonged to both of us without me agreeing things were semi civil until recently when out child was sick and I told him he can't go over there till he's better, and then he texted back saying my time is coming and I will regret this and he'll make sure and then showed up at the house the one time I wasn't there all week ( which shows he'd been keeping a check on me) and he took more things, so between the text and him coming over again after we agreed he needed to ask before he came because I wasn't comfortable with it just kinda put over the edge. I got a restraining order and the judge granted it to me and put my son on their too and he will be served tomorrow. Now my son can't see his dad for a year... I feel like this got blown up, am I wrong for doing this, I do feel like I'm in danger and so is the child I'm pregnant with but I just hope he wouldn't harm our child that's already born. But at this point I can't put anything past him. some people in my life think I did a rash decision and am not putting my trust I'm God. what do you think? I'm just so overwhelmed..
