Plenty of people leave marriages without cheating.
And whether or not we agree with their reasons, we have to admit, at least they have that much integrity.
Nobody makes anybody cheat. Period. It's a choice, and it involves deception, and many other undesirable character traits.
Above all, it is indicative of somebody with poor personal boundaries.
Now, chances are... if one person in a marriage has poor personal boundaries, you don't have to look far to find another person who has poor personal boundaries in that same marriage
