I need advice

I kinda just need somewhere to vent... I'm starting to be so unhappy with my SO. I am going to be 9 weeks tomorrow.. Which makes it so hard but he's pushing me away and i dont know what to do. He works 7 days a week and never really has a day off and he says he tired and trust me i get that, but when he comes home he doesnt ever ask me how my day was or how im feeling even like yesterday when i was having a crappy day all day and he came home and just said hi and didnt bother to hug or kiss me. Maybe im over reacting, but being tired isnt an excuse to be unloving or rude to me. Especially with my emotions everywhere its really pushing me away because he always does it! And when i mention something he gets angry over nothing. He has a lot of growing up to do, and im so scared because I only want whats best for the baby... Please help...
