Feel alone...is it my hormones?

So im almost 38 weeks pregnant and i just  started getting aches/pains in my back, hips and shoulders when laying down. My SO was being totally awesome and loving until about a week ago. He got a new job which is great. But every free second he has now he is on his phone playing games like i dont exisit. I understand he needs a break and his own time but ive told him ive been uncomfortable or ill talk about our baby or even if its something random. He just nods then starts talking about himself or his job or whatever is on his mind. Its frustrating cuz i feel like im just a ghost in the room or something. Then he will bring up how he was at work all day and making money (which is great) when i mention when he is coming to bed or if i need help with something or whatever it may be. He fractured his foot last year and I was always there for him and always helped him and he wasnt working so i was supporting us. Well now he is working he is being selfish like i didnt do anything this whole time while he was injured  and couldnt work? Is it my hormones or am i crazy?
