I don't judge anybody (well, in terms of cucking ok), they can do as they please if it's agreed to by both parties. My parents were thrice divorced by the time I was 18, cheated like mad, and basically whatever "marriage vows" they took weren't worth the paper they were written on. All that paper did was make things extra painful and extra expensive for all people involved, especially the children, when shit went south. Yes, a city hall marriage doesn't have monogomy vows, but if it's at a church/synagogue it's either explicitly or implicitly stated--cheating is grounds for divorce. I have never been married partially because I consider marriage serious business (unlike most in Dallas who are divorced by 25) and won't commit to anything if I don't plan on playing by the rules.
