rocked,
I don't know what to tell you, but what did stand out was:
1) When would "asap" be?

Alternately, if he ends it gradually:
2) When is "gradually"?
3) A last contact is a last contact. OW's potential reaction(s) would still be an unknown, would they not?

"I know it is not ideal, but I am really concerned about my kids here... make sense?"
Of course. Perfect sense.
Anyway...just thinkin'

Have a Happy Thanksgiving, Rocked.

With fruit, with weeds even; but gather them
In the one garden you may call your own."
