Anger with husband

Wife and mom of 2 and 26 weeks pregnant. I have been nothing but angry at my husband. I don't want to be around him this pregnancy which is also ironic because he's never home. He finds time for his hobbies, sports, camping, friends, family, and work outside the home. While I manage our home kids and work from home. I am finding myself nagging him and just mean to him. I keep telling him what it is I need and what it is I'm upset about but I genuinely don't think he gives two shits anymore. Case in point his parents are old in their 80s I do not allow them to watch or drive our children as there was an incident where his mom tried to take my oldest as a newborn and told her church she was going to raise him. Then when I tried to take her to coffee and talk to her she put her hands on me in the coffee shop slamming them on my disabled legs. She's never apologized and her only way of addressing the situation ever was to write me a letter of how "Christian" she is. This was 4 years ago and quite frankly I'm kind to let them be apart of our children's lives. My husband has been gone for weeks with his social life. So this weekend I made plans as I haven't done anything for myself in about 8 months. Bought tickets to the Barbie movie and told my husband I was going. He asked me what I was making them for dinner. That was his first mistake. His second was he came home from work late and I was an hour late to pick up my cousin meaning now we couldn't grab dinner like planned which I've told him about via text, messanger, and verbally. I find it so disrespectful of me when I never do that to him and I was gone for one evening in 8 months. Tomorrow I'm off to help my disabled mom so not a day off but a day to help her. He decided he was taking our children to be in a parade. Then tried to guilt me to switch my plans to accommodate him and I told him no. So his plan was to have his parents who are not allowed to watch our children watch my youngest at the parade and drive him in my brand new vehicle. I told him they were not allowed to drive my vehicle or our children and he is making me out to be the bad guy. Told him they shouldn't have their licenses much less be driving in a town they don't know during a parade and carnival with our children. That he needs a new plan. He is now outside at midnight refusing to come into our home because he's so pissed at me. I don't get a break I am disabled and do everything and more for our family and home. I feel disrespected that he doesn't consider me and how exhausted I am. I don't get days or night off and he came home late and then disregards how I feel about his parents not being of sound body or mind to be driving and watching our children. I legit just am over him and his selfish attitude and behavior. I'm burned out and am a tired wife of someone who is selfish. I feel alone in my marriage. I'm angry with how exhausted I am. I'm disappointed in him as what is supposed to feel like a partnership feels isolating hostile and not cherished. I don't know if it is the season of life we are in or if it is just our marriage. I am just burned out. I lost myself somehow and I let it happen. I allowed myself to be put last and disrespected and not a consideration in my own home. If I say what it is I need then I am the problem and I am so tired. I actually cried at the movie I finally made it to and missed the first few minutes of because of him the movie talked about all the ways a woman is contradictory and the pressure we feel to be everything and I felt it too my core. I'm worried if this path we are on I will stop loving him and stop trying from just pure exhaustedness and survival. I don't even know where to begin. I have suggested counseling but we can't afford it and frankly I don't have the time I'm already dealing with 4 doctor appointments a week and juggling the kids to and from those to keep my body up with this pregnancy. I can't afford help. And I feel alone.
