My soon-to-be ex husband had an emotional affair for about two years during our 8 year marriage. He ultimately walked out with another married woman in March. Moral of the story? The best predictor of future behavior is past behavior. If she could do this to you and allow your family to be involved, that is pretty harsh behavior. Speaking from experience, it hurts more the second time you find out about an affair than it does the first time. I would personally get out. It's the best, yet hardest, decision I have ever had to make. I know he will do it again if I keep letting him back in, so good riddance! I hope you find happiness wherever it may be
