Am I asking for too much?

Me and my husband have 2 kids together. We both work full time but I'm usually the one who takes care of the kids when we get home. He plays video games and goes out with friends while I cook, clean, and take care of the kids. My husband is an atheist. He doesn't believe in anything. I'm Wiccan and since we live in Oklahoma, my chances of finding a coven to join are pretty slim so I am part of an online coven group that meets once a week at 6pm. All I ask for my husband is that he watches the kids for one hour so I could do this coven meeting. I let him play video games and go out all the time. All I'm asking is this one hour to myself to do something for my religion and so far every Wednesday he has interrupted my coven meeting because he can't handle the kids and put the kids in office with me while I'm trying to do this coven meeting. We were talking about tarot cards today and my husband came in screaming and telling our 3 year old to go bother mommy and put her in there with me. I told him how I felt. I told him I ask him for one hour out of the entire week to do something to myself and he told me "Well you don't need to go to a meeting to play with your crystals." I said it's about more than that to me and walked away and went to play his video games. Am I asking for too much? I know I'm not but he's making me feel like I'm wrong for wanting one hour to myself for something important to me.
