“dont worry hes been cheating her for a while and she cheats him too…”
1. You are playing around with the issur of aishes ish. One is supposed to allow themselves to be killed rather than committing adultery.
2. What goes around comes around. If you do this sin, you will be ruining your life and you will probably have a hard time finding anyone to marry and if you do get married I can almost guarantee you that you will not have Shalom Bayis and your husband will probably break your heart and cheat on you.
Run away from such sins. Stay far far away from opposite gender friendships. It ALWAYS ends badly.
