FitChik, Now is not the time to mention anything about the relation and the hopes of reopening your h's heart to his faith. Right now, he's on a course of self-destruction and you must allow God to work on him in his own time.
Right now, from your comments, your h does view you as the enemy and anything about the relationship and/or faith at this time will make him more angry and defensive. Your gut may be talking to you and you are feeling compelled to talk to him about it, but I strongly advise you not to do it at this time. You will get the opportunity to have this chat at a later date.
You will need to learn to listen to what he's saying, that means, sift through the garbage he is speaking, validate and be a friend. You will need to really pay close attention to his body language because that will tell you a lot about what he's thinking. Remember, the eyes are the windows to the soul. Follow his lead for a while. If he speaks of the relationship, fine, but I wouldn't raise the issue w/him right now. He needs to settle down, focus on his issues and come to realize that you are not the enemy.
Keep the focus on you. Please allow God to take care of this matter. When the time is right, God will open the door for you to step through and then the time will be right for the conversation that you wish to have w/him.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
