I'm 6weeks pregnant now

I'm 6weeks pregnant now. So happy. ❤️ my high school sweetheart and I aren't together anymore 💔💔. What should I do? He says he doesn't want me to have it but I do. I can't have an abortion. I wouldn't ever do that it's not my baby's fault. What should I do? He all of a sudden wants to be in contact with me but never wants to talk about our baby. What do I do. I need advice. 💔💔💔
