Am I being insensitive?

Please be kind, I do want to learn from this situation.

My family and I were in Florida this past weekend for my oldest son’s birthday. My husband and our son (his biologically) don’t have a good relationship, they never talk to each other unless my husband is disciplining my son. My husbands family decided not to come on the vacation because they’re tired of Florida and that’s completely understandable.

While we were in Florida my husbands grandmother had an accident where someone ran into her leg and she needed to have surgery. My MIL told my FIL (his mother was injured) not to call my husband and worry him but he did anyways. My husband immediately left me and our children in Florida with my mother. He went to see his grandmother for a few hours, he says the injury was not as bad as his father stated and since he was back home he decided to pick up extra work shifts.

Yesterday we had a conversation, we talked about how we needed to do better as a married couple. I brought up a lot of instances where he’s left me and our children to do something for his dad or grandmother. An example of that was him being taking his grandmother to the mall while my mother and I moved out of our last place and we had 2 under 2 at that time. There’s also a time when we were stranded due to a storm and the airlines had one seat left to get home, he left me and our 3 children in an airport in a different state and my mother ended up helping me find a way home. Another was recently my car broke down, our 7 year old was with me and he told me to call my mother who lives in a different state ( I didn’t) I called a tow truck even though we were 1 mile from the house and I just needed a jump. I have many more stories just like these and I brought them up to him.

I told him he hurt my feelings, he apologized for the car breaking down thing because he assumed that I was further away from the house. I brought up the fact that he never even bothered to ask where we were, he just assumed and said to call my mother. He told me we can agree to disagree, he also told me that he doesn’t have to answer any questions I have about anything.

I do feel like maybe I’m being insensitive about his grandmother getting her leg cut and needing stitches but I don’t think I’m being unreasonable about anything else. He told me that he wouldn’t change a thing and when I started to cry about it he told me I need professional help that he can’t provide. He also told me he’s hurt too but when I ask him to explain because I do want to know and I do care he tells me that he doesn’t have to tell me anything and then he started getting agitated.

Am I being insensitive? I do want to be fair and understanding.
