My heart aches for you. I think the only thing you can do is see what he decides from here. I would tell you not to wait forever. He probably is a caring man and DOES care for you and his daughter. It is the extent of what he is willing to do to keep you in his life. You have ALLOWED him to stay married and not make any more of a commitment with you, so the status quo has changed now that his wife knows. She may not even want him per say, just won't want you to have him. There is a reason they have been married for such a long time though....so many different things are happening right now in all of your lives. A lot of men like the idea of having more than one woman in their lives, each compliments a certain part of who he is....it is not right, but that is what they do. I would seek some counseling if I were you....if you don't attend church, go, look to God. He works miracles in people. Adultery is a sin, but God is also forgiving if you ask for it. I do feel your hurt and frustration and your absolute desire for the best outcome for you and your daughter, and trust me, no matter what happens with this man, you and your daughter will have a good life as long as you leave it in God's hands. Just say a prayer to him, "God, I do not know what will happen with this, but please lead me where I need to be for myself and daughter."....even if you are not deeply religious (it may sound like I am, but it is more a knowing how He has helped in my troubled times, and I HAVE HAD PLENTY of those.) Like you said before, see what he tells you and know that action ALWAYS SPEAKS LOUDER THAN WORDS! If he says he will leave her, then he has to leave her immediately, not in 3 months or 6 months or never....it cannot continue the same way anymore.
