Husband jealous of deceased friend (HELP)

When my husband and I found out we were pregnant we agreed that he would get the first name and I'd get the middle name. We're having a boy and I want his middle name to be Bravon pronounced (Brev-inn). I had a friend who passed away last year and I told myself I'd name my first baby after her. This was before my husband and I were together. At first he had no problem with it but he soon became jealous of the fact that I'd post about her on Facebook. He also says it's a girls name which it's not. So he went back on what he said about who gets what and told me I'd only get the middle name if it's a girl (which he never said) he's never met her but despises her because I choose to keep her memory alive on social media it's not an everyday thing it's probably once every couple months or so or if I see something that reminds me of her. I feel pressured enough because he wants things to go his way and tells me no about the name to the point that he gets angry, and for that reason. I'm the only one bringing in income which is hard while he claims to be waiting on a job but I come home and he's playing video games. He hasn't bought the baby anything. I feel like since this is my child too I shouldnt have to go thru hell just for a name. I've thought about just putting it on the birth certificate because he won't compromise. But then I feel like he'll make my life hell and try to manipulate me. I just don't know what to do.
