I don’t know what to do

My husband is a slave to his mom. He works all the time and I never see him only for dinner and bed but before he comes home to Me tonight (his pregnant wife) he goes to his moms house. He asks me to put food on the grill and I do and then he gets mad because I didn’t cook it right and he says he has to go back to help his mom with something we argue back and forth and he walks out taking not only his car keys but mine as well so I can’t go anywhere. I don’t know if it’s the pregnancy emotions but I feel so unhappy he never spends time with me. I texted him and told him to stay with his mom and that I’m going to bed. Am I overreacting? This happens all the time I just feel so alone.
