There isn't one. That's why they call it cheating.
only if your dating the person that cheated on you
there is none, it is wrong,
Yes it is possible.
No. It is not possible to truly love someone if you've cheated on them. If you've cheated on them, then there's obviously something about them that you don't like and you are seeking someone else who has the quality that your person doesn't have. If you truly loved someone, you wouldn't have cheated on them in the first place. It's probably best if you told them the truth, and just moved on with your life. If they forgive you, then great. But if not, just move on. There's no point in trying to mend something that had issues to begin with.
If he cheated while you were a couple , you may never know, unless someone talks. If he did after you split, why would you care ?
fess up. And don't do it again.
Of cause it is acceptable! If it's the culture of someone then i think there is no reason why it shouldn't be acceptable.
if someone cheated on you i would kick her or he to the curb because once you cheat you going to always be a cheater. most of the time
you will know if your cheating when you are dating someone and dating someone else at the same time.
move on... you deserve someone better -coco-
If he cheated on someone else with you, then you are next.
It depends on how old they are. In general, it is acceptable.
