I know what you're saying, but there's not much else I can do. Had this ended two years ago, it would have been because of her affair, and my three oldest children would have known that, been TOLD that, and the youngest would have been told eventually.
Had she not ended her affair, that would be one thing.
Had she not gone to counseling, that would be another.
Had she not gone to Retro, that would be another.
But she ended her affair, remained by all evidence (and I did continue to check) a "good girl" for those two years, went to a few MC sessions with me, went to Retro with me, cooked my dinners, did my laundry, and made all the minimal outwardly-apparent efforts.
So what am I supposed to say, that "Yeah, but it wasn't ENOUGH???
Besides, at this point, I want out too. 20 years of a sex-starved marriage is quite enough.
