interesting how the father (you) is more interested in the kids than the mother. do take care of them, but do not lie to them about your situation with your soon-to-be x. the need to learn how it should be, not have an example of a normal broken home. can not show them a good example with her, because she does not want it for you or them. she wants to feel desired, by someone else.on this one, i disagree with you.
if you're lucky you will get 100 years of life. you can not get back even one second, ever.
the proof is that if she wanted to actively work on things with you, and stay, and try in the counseling, and respect you, then you would probably invest every ounce of energy you could to make it work. SHE DOES NOT WANT IT, she wants attention from someoneELSE.
do the red pill improvement plan. it can't hurt and no matter what will help you in many ways.
if you are a good man, your kids later in life will copy what they remember you did.
