My dear, you don't sound well. You should meet with a psychiatric for medical check up.
You should have consulted us before the act. even at that, you still sound satisfied and justified with your actions, so what other advise do you need from us?
Guys, I guess you are missing something here. The question is " CAN U CHEAT ON UR SPOUSE AS A REVENGE?". Whenever spouse is mentioned what comes to my mind is married couple. If I have a spouse that cheats (God forbid), I wouldn't want to cheat on her as revenge, because i will be doing myself more harm than good. What if i get contacted with diseases or even die in the process? This also is not in line with the word of God. God says "vengeance is His". The best i can do is to divorce her and have my peace.
