When cheating happens, it damages more than just the marriage. It also destroys “friendships” as well.
I have no problem questioning how Christian someone is who supports a Cheater over the faithful spouse while fully knowing of the infidelity. Minimally, they are NOT friendship material for the faithful spouse.
Further, such people have different values than I have. They view adultery as less problematic than the Bible does (and I do).
It hurts thinking of some of these individuals that I had once thought were friends. They sided with Cheater even after learning of the adultery. Nary an apology for getting the situation wrong prior to such a nasty reveal.
