My W trying to make it sound like she is running away on some victim story. Making it seem like this is all my fault. Completely ignoring the A aspect. I simply plan on telling that though we have had issues over the years. Issues that could have been fixed with communication, she didn't want to bother. But instead wanted to carry on an inappropriate relationship with a married who had a family of his own.
Tread, even though I got a little flack from how I handle the discussion with the kids this is what I said/did. My WW wife started out saying that... "kids you may have noticed that dad and I haven't been talking much lately and not really getting along, WE have decided to get divorced". That's when I stopped her and said kids..... "I do not want this, your mom is the one who filed for divorce and no longer wants me in her life. I just wanted you to know were I stand on this. I told them that we will both love you no matter what happens and you are our number one focus!!" I did not mention the lying and cheating because honestly, kids are smarter than any of us give them credit for and they will find out! Everyone I know that is going through this or been through it they have all told me the kids find out! Keep your anger harnessed and use it for good, I have/had anger issues but with IC I have used it for good and I am much better off for it, and my kids really appreciate my new approach with them. Good luck,
