The 80/20 rule.
If s/he has 80% of everything you could ever want in a relationship, don’t be stupid and go off looking for that missing 20% in someone else. I guarantee you that when you find that missing 20%, you will miss the 80% that this new person doesn’t have. Then you’ll either have too much pride to ask for forgiveness or have no shame at all and beg for it.
We 80% folks put up with enough of your crap as it is. And I won’t stick to someone who doesn’t realize what they have when they have it.
20% is a FAIL.
