What would you do? (marital 'infidelity'?)

[Major Nikon]

82. Actually in the vast majority of cases that's just a symptom and not the actual problem

By the time it gets to that point, there's already a lot that has gone wrong in the marriage. And being happy is not necessarily the answer either. Some people live with chronic depression and still manage to maintain successful marriages. Most of the time it really boils down to how people deal with conflict and how they communicate with each other. All marriages will have conflict. Some of that conflict may never be settled, but generally most can. When couples don't deal with their conflicts, this leads to contempt and contempt erodes the marriage. Cheating generally happens towards the end after a lot of other things have gone wrong. Even when marriages get to this point, it doesn't mean the marriage is nonredeemable. Lots of couples manage to get past infidelity and rebuild troubled marriages. But in order to do this they have to address the actual problem, and not just the symptoms.

Furthermore these things don't just apply to marriage. They apply to pretty much all relationships including professional, friendships, and all types of family relationships.
