It is frustrating to say the least. We are in a similar sitch. Have you seen the movie Husbands and Wives by Woody Allen. The H goes through as similar affair and realizes what an idiot his OW is when he introduces her to his married friends and she tries to convince them of the benfits of astrology and eating tofu.
A person who associates with an older married person may be beyond selfish, they may have had some abuse or loss in their past. Listen to Dr. Drew on Love Lines. He always presumes that these young women with low self esteem have had some sort of sexual abuse or loss in their past. They need a therapist not an affair. What happens is the WS needs to feel better about themselves so they see an OP who is even lower and needier to reflect their manhood. I am conjecturing here.
You must live as though you will be happy on your own. Do not act needy as it will seem manipulative and unattractive. The idea of attracting a H is ludicrous as there used to be a circle of trust that seemed unconditional, but we are no longer dealing with a rational person.
You must know that the OP is truly irrelevant. So is OP age or anything they appear to offer. It could have been anyone. There is nothing special about them so we must not empower them with snooping or tears. Do not glamorize the affair with drama. Be postive and agree. If he says anything, do not try to convince him of the opposite. Just agree within boundaries. If he says, "Our M was a mistake." Do not argue or he will take an even stronger stand in convincing himself he is right. Just agree. Be mysterious and act as if you have a life also. Which I am sure you already do. You don't have to be better looking or go through a MLC yourself. You just have to love yourself and remember who you are. Never give up your self esteem no matter how big the blow is.
