Am I being unrealistic

I keep telling my husband I'm overwhelmed with the kids. I keep saying I need time away. I'm basically fed up at this point. My husband has had poker nights, casino nights with family, lunch, dinners, and many times in the past few weeks to see friends also time alone to work on house projects.

I have had three kids with me continuously for a month. The exception is when the oldest is at school. But as a stay at home mom I'm the one up all night with the teething toddler. I have them solo every weekend while he has plans.

Yesterday I took the kids to the zoo while he worked on house projects. When I came home with dinner. I told him I needed to lay down as I pulled my back and shoulder. Again I haven't had alone time for over a month.

He got the kids to bed alone after dinner.

I was up most of the night with the toddler. All kids are home today and tomorrow. So I'm feeling overwhelmed by the constant need and stimulation.

Husband text me he's working late then going to the dentist. He doesn't have anything wrong with his teeth he just got the option to move up his appointment.

I think it's insensitive to do that to me when I have been begging for help. I will be solo again until tomorrow evening then because I will be home alone all tonight and tomorrow.

I vocalize what I need and my husband's response is things need to get done or he's trying and it's bullshit he isn't.

My needs are never a priority. I'm overwhelmed it's on me. It legit feels like the doesn't give a flying fuck on what I'm saying. I'm so resentful and I'm burned out.
