I don't know what to do

So, I found out I'm pregnant. And when I told my boyfriend which I live with, and we will be getting married soon, that I am pregnant. He sort or freaked out. He's not ready, he's scared to be a father. And he hasn't even touched my stomach since I've been pregnant. But sees little kids and gets so excited and will show me pictures of little babies . But won't touch my stomach. It hurts me so, much that I wish I wasn't even pregnant , he makes this experience not even joyful,. This is my first time pregnant  at 25 years old.  He makes me just wanna give up sometimes, I threaten to leave him and just raise my baby on my own, he says that hurt him so bad. But why do you act this way. I don't understand . I just want him to touch my stomach.  He keeps comparing other people and their ages when they had kids. They waited . We should too. Well I guess we should wait in having sex too. I just don't know what to do anymore 😪💔💔💔
