Time passes. Maybe it's better to learn her true nature now, rather than ten years into the future. You are still a man in your prime. You have two children who seem to think a lot of you.

You have ten years worth of experience in life that you didn't have ten years ago. Recently, it's been very painful experience. Let what you're going through now inform your relationships with women in the future. Sooner or later, there will be another woman. You can come out of this painful marriage with a more mature appreciation of what you need in a woman. Gaining maturity is never a waste of time. Usually it does involve pain.
