Husband tries sexual things with me when I’m half asleep

There have been multiple times where my husband has gotten sexual with me while I’m half asleep. Examples include touching me sexually, waking me repeatedly to further push me, asking me to help jack him off, pushing me to have penetrative sex, etc. I feel like he takes advantage of my half-asleep state, and it makes me uneasy. I’ve spoken to him about this, and I’ve withdrawn completely from sex with him because of boundary issues. It’s happened again, and it’s only made me trust him less. He doesn’t seem to care as long as he gets his release. I’m too tired to even argue it when it happens. My body just feels heavy with sleep and my eyes can never stay open.
