I think I'm going through my first pregnancy alone ?

I went to my bf house and he had his door locked ,  I knocked on his door and told him I need to talk to him it's important and he said he doesn't wanna talk and then called my name to like leave him alone . I told his mom I was pregnant and she seemed happy .. I don't think he's going to be involved in my pregancy I think it's over between us??  
​His mom said either two things can happen he will get even more depressed that I'm pregnant 
​Or he will improve for the baby ? 
​I'm so emotional I'm 6 weeks and 2 days wtf am I qunna do I haven't even told my mom
