I'm curious as to how much -- if any -- you all would change your advice here if the marriage were effectively dead, by mutual consent. In other words, two parties agree that it's not working, they've tried everything they can do, and they agree to either separate or divorce, but it' takes awhile in their state. One spouse wants to date -- probably while the two spouses still even live in the same house, but with some "rules" -- while the other says "we're still married; you can wait a few months."
I have a friend in this exact same situation.

Based on my prior M, after my D my xW wanted to come hang out at the house all the time, but seemed happy we were D. The first time I had a date post-D she burned up my cell phone screaming at me, then showed up half-naked on my doorstep crying to take her back.
I guess the moral is, you never know what kind of effect sharing space with someone will have on the person who isn't dating.
