It’s impossible… BUT DOABLE!!
This is a quote from Sean Connery in the movie "Entrapment". I love that movie, I live that quote but I HATE that the FB, my husband’s ex mistress, has it tattooed on her shoulder. 😖
I am very sorry you are here. I know you feel that 12 years of your married life were stained by that lie. You are right to be disappointed, angry and shocked.
Whatever you feel is your right but it will not erase that hurtful reality.
That event and his decision to keep it secret for such a long time is now part of the past and the past can hurt you only if you allow it to hurt.
I come from a country in Europe and I read some blogs on this sad topic. Many cheaters say that confessing an affair is stupid because it is in the past, it will badly hurt your spouse and if the cheater discloses it just because it is too hard a sense of guilt so they want to come clear, the pain they cause is not worth it.
I am just explaining how some people think. I completely disagree because despite the pain it creates, it gives the betrayed spouse the chance to make an informed decision "To stay or to go?" and maybe, if they decide to stay, to work to improve the relationship that should never be based on lies.
Unfortunately your husband has kept this secret but I wouldn’t see it only negatively, there might be two reasons:
1. He wanted to look better than he is, so he hid a big flaw.
2. He didn’t want to hurt you and somehow he wanted to protect you. He had not been able to protect you when he slept with that woman but at least he wanted to protect you from pain.
So why did he tell you now? It is evident that the lie was making its way into his soul and crushed it. He wants to be an honest person and show himself without a veil, "naked".
You will have to grieve, it will be hard, but you can do it, if you want. Keep us posted.
