feeling down

Sarah
Im 15 weeks 6 days. And i feel like im losing everything. Moved in with my partner beginning of april. And over the past couple of weeks he spends alot of his time upstairs in our room. He works 4am til 7am everyday so has few hours sleep when he gets home. But soon as the kids are home from school he goes upstairs and hell be up there until he gets up for work. Iv tried talking to him a few times and all i get is i just want to chill. He says hes gonna go fishing or to see his mum and when i say ok he says dont matter i wont go and then tries to say i dont let him do anything. I dont think he wants to be a family. 
I dont have anyone to talk to, my best friend doesnt talk as much to me since ive moved she didnt want me to i text her everyday and even try to call. We share a special day the day i had surgery for my miscarriage surgery wasnt planned but i got really poorly she had a emergency c section she was really poorly too. And my mum isnt speaking to me because i didnt my facebook status that she commented my problems on im having with my ex.
Anyways thanks to anyone thats reads my post im just upset
