Wendy, You are not deserving of what you are going through. Your h is a grown man and should have enough respect and love for you not to be hanging around w/the ow. He does know what the word "no" means and since he's in some type of crisis, he's going to have to learn what that word means all over again. The ow is nothing more than a sick individual who feeds off of weak men. Once she gets him and has sucked the life out of him, she'll toss him away too.
Hang in there!
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.
