do you believe that there are certain circumstances wherein cheating is ok?

I really can't think of any circumstances where cheating would be ok. If your marriage is ending or going bad, or if you aren't happy with things, don't cheat. Talk to your partner and actively decide to end the relationship. Don't go out behind their back,get your kicks and come home and pretend like everything is ok. End the relationship before you do something stupid, do not cheat.

Absolutely no way! Their is no reason, excuse, circumstance at ALL to justify cheating. If things aren't working out for you and your partner in the bedroom or if you have feelings for someone else and want to explore those feelings then break up with the other person. Then it is not cheating and the other person doesn't get hurt as bad.

honestly if you are in a saposed loving relationship then there is NO reason what so ever for either to cheat on the other. Iam sorry but I dont see a reason to cheat on any one at all.

no, if you want another person or persons you should not get married. it just courses hurt

I would have to say No ....If you dont want to be with that person they need to talk with their partner, It really hurts and its truly not worth it .....

I think there isn´t a circumstance that anyone is allowed to cheat in a relationship. And I dont think that the "I was too drunk" is an excuse. When we are drunk we still know what we are doing. That´s my opinion.
