I don’t blame you for wanting to confront. If you do, make sure you have proof first.
What’s your plan after confronting her?
For the record I believe confronting/exposing her will take away some of the thrill. It also allows you to state your boundaries, and feel some control.
She’s addicted to the chemicals the brain produces during an affair right now, and won’t give up on that easily. Normally this lasts 6-24 months, but I’m going to guess that the huge difference in age here will cause this affair to die off at the earlier end. The puke is not going to sign up for any long term relationship.
Hang in there THX. You've been dealt some crappy cards... play them well, my friend.
M: A really long time. Crisis: 5 years. She's still worth it.
