Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
I'm no expert, but I think it's important for you to recognize and accept that this man may not have EVER had neither yours or his wife's best interests at heart. It's pretty cruel of him to wreck both of your lives through his own personal selfishness, in my opinion. I do hope, for the sake of your emotional well being, that you don't intend to reunite romantically with him. I fear it would only lead to your own betrayal (worse than this one). Perhaps it is best to cut off ties after you situate your financial problems. Take time to heal and grow from this for yourself.
Perhaps apologize to the wife somehow? I hope you find some form of calm after this storm.
