This not about morality. This is about where you want to focus your energy, what you want the outcome to be and if you are ready to man up and take this seriously.

Flirt, get attention...whatever but if you are ready to bone down with someone then get out first.

Is this how you want to spend that last month of trying to make it work?

Come on dude, make a plan and implement it or don't waste everyone's time.

I'm riding you a bit here probably cuz my H took a similar approach. Says he "tried" but had some lovely ladies tugging at his zipper while we were in the last leg of our "trying to stay together"...but they had "nothing to do with" him leaving...hmmm...check yourself.
