''The sex stopped after kids''.... Sadly this is such a common problem.
Children massively change a relationship, {I'm a woman who was cheated on by husband} ..and if there is any weaknesses in that relationship, children will act like a wedge..as the more immature party cannot bear being 'taken for granted'.
The REAL losers when a marriage splits up from infidelity are of course the Children.
The adults hurt, but the kid/s really pay the price.
Men 'DO' think differently to women, they are more visual, more able to compartmentalise , and tend to be more selfish {generalisations here, but just what I have observed}.
IF your wife is good enough to 'give it another go' {I wouldn't!} be prepared for her to be very anxious, moody, distrusting &c.
A young woman said her dad had an affair, and they 'gave it a second chance' but her mother has some real deep seated anger and resentment 20 or so years later..... He pays. Still.
Counselling may help, but once trust has been betrayed, it is like when a precious object has been smashed....It can be repaired, but is never quite the same again.
And as for Suicide..Please do not do that...Children suffer so much when a parent does that...it isn't the right thing to do for anyone, you or your family... things always improve.
Good luck.
