Going depressed

Lately I’ve been staying up late just laying and thinking of what to do now me and the guy I’m having a baby with I would call him my boyfriend but I’m unsure where we stand anymore lately he’s been distant and we haven’t had any conversation face to face in over a month and we live under the same roof I have no idea what happened between us and I’ve been going depressed because I no longer know what to do with our baby I’m 30 weeks pregnant 16 years old and he’s 18 years old I try asking him and telling him how I feel and his response isn’t the best he doesn’t care anymore and I worry he is going to try and take our baby away from me legally he’s said it many times before that he was gonna get a lawyer because my family always just talks about doing things with the first nephew the first grandchild I don’t blame my family for saying things I know none of the stuff they say they are gonna do is true because they hardly have time but his family on the other hand doesn’t talk to me they don’t say anything about the baby and he tells me that he feels left out that I don’t include him when I do when I show him photos of nursery ideas he plays a game on his phone or he just ignores me and it truly hurts me and I don’t know what to do anymore about it.... please help
