(((Mojones))) I'm so sorry you are here, but this is a great place for support and advice.
I agree with Piglet, he did invite you to go out with him and that is good. You listening and not getting defensive was good too. The sex thing would bother me too, but treat it like you did/would do if you were dating someone new. Wait for H to initiate. You can even make a game out of it. Tease him a little (dress differently, make some changes for you) and see what if any reaction you get.
Mainly, stop focusing on him and what he is doing and focus on you. Make changes in you that help to create some PMA for yourself and let H figure out his stuff on his own. If he is confused then its something he will have to work through.
