Stay at home wife

I am a stay at home wife. I have been for 5 years. My husband and I are financially stabled to do so. I have decided to return to school so we can comfortably afford the lifestyle we like (everything has gotten expensive) and have been doing so. He says he can support us but i just want this for me and us to be more successful and comfortable. However, when my husband and I argue (even when it has nothing to do with the argument) he brings up that I don’t have a job and haven’t worked in 5 years. Also, we don’t have kids. Lately I feel like my life has been revolve around him, his job, his schedule and he doesn’t see how much I’ve sacrificed to accommodate whenever something comes up with his job. I don’t know, I am confused I guess. Yes, I am a stay at home wife and I love and enjoy cooking taking care of the house and we go on vacations but it’s like he belittles me when he throws that in my face. It just doesn’t sit right with me.
