Dragon,
I've read several of your posts but haven't had much I could contribute. I'm experiencing some marital issues myself and there is a lot of emptiness in my relationship too. I think you are doing a good job of giving her the space she needs. Maybe instead of a big passionate hug, you could try to express your feelings and continued desire for her with a squeeze of the hand or something more subtle. Something that can be acknowledged by her but doesn't need to be reciprocated at the moment.

I know you are not my husband; but sometimes the big hug or passionate squeeze is just too much. It raises fears that if you accept it, your going to be dragged into the bedroom. It's nice sometimes to feel that your husband appreciates you and is still interested in you, but acknowledges that your still working through stuff. Subtle physical connections without strings would send me this message without me feeling smothered. If she feels like reciprocating she can then choose to return the squeeze or move closer for a hug. But don't expect it. She may need a few subtle connections before she realizes that there are no strings attached and its safe to reciprocate. Just know that your efforts are likely registering and communicating to her your desire to be with her.

Just some thoughts from the planet Venus.
