Feel trapped!!

I’m 29 yrs old and have been with my husband for 15 yrs married 6 and we have 2 kids ages 11yrs old and 4 yrs old. The last 2-3 yrs of our relationship hasn’t been good he questions me for a lot of stuff he never has before he is always just a dick to me about everything I say or do and I don’t do anything that he should be questioning like for an example when the kids and I go over to my sisters and we are there around lunch time every time we get home or when he does he asks “What you guys eat for lunch since you weren’t home” and I tell mine he ate there and he asked “What did you eat” like he needs to know what we ate and 1 time I said we ordered pizza and he go so pissed Cu I spent $14 on pizza and a few drinks for us but he can go to the liquor store every week sometime twice a week to get a 30 pack of beer, and he always questions what I do during the day. I’m just done with being treating like shit but I have no where to go we live in a small town and I have no family close by

I’ve tried talking with him about our relationship and now I’ve been feeling but he thinks nothings wrong with it and it’s all in my head and I’m just being dumb. He don’t believe in talking to someone about our relationship or anything, his own father has noticed how much he has changed when it come to his anger issues and how he talks to me.
