In this type of scenario, love and family is the least of things to consider.

The two most important are your mental health, and your ability to trust your wife.

If you stay in this marriage, are you going to be able to trust her? And part of that means, is she willing to do whatever is necessary to regain your trust? And that doesn't mean you say you forgive her and then everything is swept under the rug and forgotten.

The most important aspect to consider, is what will staying do to your mental health? For me, I knew there was absolutely way to reconcile with my ex, because I knew staying would eventually eat me up inside. I didn't want to fret everytime she went out, or was on her phone.

Do what's best for you, NOT your kids, NOT your wife, but you. In fact, the best thing you could do for your children is to ensure you're in a good place mentally. And if that means you get divorced, then so be it.
