What is he trying to do?

So my husband and I are divorcing. Lately he has been all over me. We have not had sex in over 6 months to a year and I dont know if he wants to work on the marriage (which even if he did i'm not stopping the divorce) or if he just wants sex. When I mention the paperwork and how I have filed and need to serve him his copies he acts like he doesnt want to talk about it like he is rethinking the divorce. I need to know why he is doing this. When I ask him he says that he thinks the divorce is the best thing but then acts the complete opposite. I'm so confused.
