I feel stuck..

My marriage has been so rocky since I got pregnant with my 2nd. Our arguments are getting worse and worse. If i didn’t have kids I would leave him. I have also not been working as much for the last 2 years and I feel so dependent on him financially that I just feel even more discouraged and stuck. I have no one to talk to. I do have a therapist and we discuss some of the things I’ve been dealing with. We live in a state where I have no friends or family. My sis in law lives with us. I’m just so unhappy. When he gets upset he says such horrible things to me. I feel so sad like I picked the wrong person to marry.
