If you guys are in an extremely unstable marriage and she is hanging with other men (cheating?) getting out of the relationship will probably be better for your kids.
Take this from a guy who is 19 - My parents divorced when I was one. My dad remarried. Three or so years ago my step mom cheated on him, they've fought a LOT since then. My 14 year old little sister (who was their child, not my moms) wants them to get a divorce as she can see they should not be together. They, as far as the rest of the family can tell, are staying together "for my little sister". It's hurting her, and my dad and step mom, way more than it would if they just got a divorce. Sometimes it's for the best.
If divorce brings your children out of a toxic environment; it will do more good than harm. I can vouch for that. Please don't feel remorse for ending your marriage. Your kids will understand when they're older, if they don't already.
