Ashlee, I can add that from a man's perspective (and I think I am still a man), what he is trying to do is not surprising. Most of that is based on the different ways men and women approach sex. But, for a man, sex does not always equal love - in a healthy marriage it does. So, you are not showing him a lack of love by doing what is right for you.
Your H has to know and experience the consequences of his choices. You cannot control his actions, but you sure as he!! can provide the consequence here. Your reluctance to do so, while understandable, is actually delaying the process that needs to play out.
If he does not come back, it will not be b/c you would not sleep with him. He may want you to believe that, but it is not true.
