Wife wants best of both worlds

[MHL]

Are your kids aware that Mom and Dad are divorcing and what that means? Do they know that Mom is "dating" another man and they have not met him yet? What do you know about him? Has he been married before? Kids, Job etc. The reason I ask is that your wife is still in the "in love" phase of this R with OM and when there are some external pressures put on the R, it will more than likely will crumble.
It is easy to say but hard to do, as I well know, but GAL and be the strong confident MAN she met so many years ago and when that R falls apart she will come running back to you. From one father to another, I admire you for being the "rock" your kids can rely on, make sure YOU are the constant in their lives right now.
