Not sure anymore

My husband and i married in Feb of this year. We have known each other for 10 and dated on and off due to him being over seas. He actually would break it off. but this last time we decided we wanted to settle down. We have been getting into stupid fights because he does what he wants to do and doesn't think of me and the kids (no they aren't his but he wants to adopt) when we fight I'm like maybe we should just go our different ways cause I'm tired of fighting. And he is like we aren't divorcing I don't believe in it. a day or 3 goes by we do good then bam another fight. He has ptsd really bad and juat had surgery on the 27th of March which put him out of work for 6 months with no weight on his right foot. times are stressful but still. I have been taken care of him and both children doing what they want when they want and no one has asked about me. well this morning I woke up sick af and had to be seen at the doctors this morning who said I had strepthroat and needed to get medicine and go straight home to relax and rest. My mom came and got my youngest child and will be picking my oldest up for school after he get out to keep them so I can rest but my husband ha. He doesn't seem to think I need rest he fixed him soup never asked if I wanted anything , he took a bath that I had to help him with due to the surgery never asked if I needed anything. I thought when you got married it was for sickness and in heath on both parts not just one. My mom says I'm over reacting but damn what about me. I am so stressed out that I am now sick and still no one cares how I feel it's all about him. idk what to do any advice????
