Let me start by saying I don't know whether D or R is your best option. Let me also say I hope you take my whole post to be observation and support, not criticism. Also, this whole post is JMO.
I think that you've given up your power and taken on a heavy Victim role in a Drama Triangle.
These things you've said especially bother me:
If our marriage was so bad I always told her to give me a D and not screw our family.
What kept you from understanding that you can decide to D, too?
but her bitch of a AP was just better
But he's not - they ALWAYS affair down. If you D because you think he's better, you'll still think he's better after you D, and you'll till be swimming in shit.
I urge you to first reacquaint yourself with your strengths, your ability to love, and your lovable-ness. Then decide to R or D.
I’ve been defeated all the way around.
All you've done is make some choices that didn't work out - due to factors beyond your control.
You can get out of infidelity by D'ing, but infidelity seems like a 2ndary problem right now. The big payoff for you is to realize that you're capable, loving, and lovable, that you have the power necessary to make choices for yourself, and that you have the power to make a good life for yourself and your kids.
Yes, your W hurt you terribly, but your core is strong. Now you have to decide to like yourself enough to allow you to heal.
I know you're in pain ... but you're not doomed to hell on earth. Being betrayed happens to the best of us. It's not about us - it's about the betrayers. You can hold your head high even though your W cheated on you.
Because you don't see your life this way at this point, I urge you to find a good IC to help you get out of your awful, excruciating funk.
Again, reacquaint yourself with your strengths. See that you're loving, lovable, and capable. Figure out what you want. Then the decision between D and R will come from strength. Then the decision will put you on a path to a life worth living.
BTW, the quote from your W is something a good candidate for R would say. She could be faking it, but if she's genuine, R is possible for you - if that's what you want.
Find a good IC, TH. Tell him/her that you feel like shit and want to feel like a human being again. Ask the IC if s/he can help with that. When you find one who thinks s/he can, go for it.
