Sorry to hear that

Feel sorry for yourself a few weeks then move on. Cold I know but just accept it. Good on you for helping raise her kids. Takes an unselfish man to do that. I have a hard time believing a " christian woman" or decent would just leave a man after he helped raise her 3 children from another man. I think you know what I am getting at.

I see time and time again that women in their 40's just leave a marriage when it is convienient and financially feasible for them. Of course men do it too.

Seek out the top ten or so DIVORCE attorneys( female is better) in your area. Talk to them so she cannot go use them after you.

After a year or so you wonder why you did not do it sooner.

Prayer for her kids and you. The youngest kid will probably need more support than you.
