The engagement is off...Should I name the baby what I want to name her?

Mo
My now ex fiance took his ring back like 2 months ago because of something that happened when we were broken up. He said we can work it out but still hasn't given me my ring back. During the pass two months he's been very disrespectful. We are in a long distance relationship and I drove 10 hours while pregnant to spend a month up north with him. The plan was for him to come back with me since our little girl will be born in August. I'm still up here but I'm leaving tomorrow. We got into a fight last night and today he says he is not coming down because his son playing football. His son is 10 and he knew that the plan was for him to come home with me to help out and prepare for the baby. I have no help home. I'm not begging him though. He can stay. So here is my question...He wants to name our daughter something that I don't care for that much. He might not even make her birth so should I just name my baby what I want to name her? I'm sick of him being disrespectful and inconsiderate. I'm freaking 33 weeks pregnant and all he wants to do is fight and argue. I'm going home. Screw this!!!!
