Thanks. I guess I just find it odd that you seem to still classify it as an affair, when he's already divorced you.
My advice, sadly, would be for you to try to get whatever IC you need in order to help you move on. I know it hurts, but I think your husband tried to give you a chance and you continued your contact with your trainer, and this was obviouisly a dealbreaker for him. Just live your life, try to grow/learn/self-improve, and then who knows what the future might hold? Something like 20% of divorcing couples end up re-marrying, with most of them reporting that the marriage is stronger and healthier than ever before.
