Solo15, you are still in emotional shock. you found out this week. Think all the thoughts you want but please don't make any decisions for a while. I would recommend not lashing out verbally to your wife, kids, or family until you emotional stabilize. I was a basket case for about a month after I learned about my wife's EA/PA.
It's weird you said you sensed when PA occurred. Me too, I swear, it was lunch time on a rainy Wednesday in December. I was calling her work phone, cell phone and texting. I just knew something was happening.
Solo15 free yourself from the cage you have put yourself in. Don't be a prisoner, don't view yourself as that. Mourn for your marriage, take some time and reflect on what you truly want. Then you with us at your back will find the way there.
Pain in life is inevitable, suffering is optional.
