It just doesn't sound like you're at that point yet Floyd. Of course you want that, and it'd make you feel better in the short term, but do you think it'd help fix your M? I'm all for having fun, some innocent flirting, but dating is a game changer.
Two things bother me in your scenario:
1) Your W has an awful lot of hostility right now but remember, she is looking for justification for leaving the M. She has to demonize you to a point, rewrite history, etc. When you are doing 180s it's hard for her to find that justification, so she lashes out to see if she can find the "old you" in there, to find that justification. My W actually treated me like crap for the better part of a year in order to "get me to leave"....but I'm too stubborn or too stupid
2) Have you given your very best to the M? Do you feel that you have exhausted every avenue? Have you become a man only a fool would leave? Sometimes I have thought of my W's past behavior as a sickness. Would I leave her because of it? It'd be hard, but no, I wouldn't...I'd want her to stick it out for me so I'd do the same. And I'd also want my kids to see that sometimes M is hard, but you don't simply give up.
