Interesting question..
If one is “allowed” to cheat, is it still cheating?? Who is “allowing“ said cheater to cheat??
How I see it, no sane individual would grant someone permission to cheat. No sane person would ask permission to cheat. A cheater will cheat because they dgaf about the emotional damage it may cause to the cheated significant other.
So, my answer to the question is this..
If someone cheated or is currently cheating before the marriage, then there is no specific time to wait until said person cheats again. The cheater could cheat on the wedding night or the night before, if there was time to do so. The cheater could also wait until the honeymoon is over, then go back to cheating once (s)he get back home.
No cheater asks permission to do so. They just do it until they either get caught or grow a conscience and stop on their own..
I don’t understand why people would get married when there is a lack of transparency in their relationship???
