fess up. And don't do it again.
Let him have her, and find yourself someone who respects you.
only if your dating the person that cheated on you
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 ?
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-
There isn't one. That's why they call it cheating.
If he cheated on someone else with you, then you are next.
Just move on and realize that there is someone else out there for you. Also know that you can get past them because if they were real with you they wouldn't have cheated in the first place. And if they wouldn't have cheated they wouldn't have had anything to lie about it.
Are you the person they were cheating or was it someone else? If someone was cheating you, I would say I didn't want to be their girlfriend (or boyfriend if you are a guy) anymore and that I saw them cheating. If it is someone else that was being cheated, I would tell the person who is being cheated and tell the person what I saw the person do.
