Desperate for attention

My husband of 23 years always goes to bed before me. I am the one that tucks the kids in a makes sure everything is ready for the next day. Once I finally get to bed there is a pillow in between us and he is rolled on his side asleep away from me. I have explained how bad this hurts me and how I long for him to hold me. He acts like it is no big deal and never tries to wait up for me or ever engage in any meaningful conversation.
