This is a tough question Chi and I don't think there is a simple answer. Trust is earned and that will take time.As far as your emotions are concerned you can't let it eat you up. If you are going to forgive him then do it and wipe the slate clean.You have to truly let it go ,don't bring it up every time you have doubts.If you are unable to do that;Then it is probably better to move on.
On the other hand if he cheats again then there is probably no way for you to establish an open line of communication and trust. Psycologically most people that cheat do it out of inadaquacies and insecurities that they face , rarely does it have anything to do with love.

Trust is something that must be earned. When you give your trust to someone and that trust is betrayed it is very hard to get it back. First you must tell your boyfriend that you will forgive him for his transgressions but make him understand that it must not happen again. Let him know that you forgave him this time but if there is a next time you wont for any reason. Tell him that it hurt you very much,you like yourself,have many good qualities to offer a man and you will find someone who will appeciate you even if he doesnt. Let him know if it happens again it will be over and there will be no second chance."I DANCED WITH THE DEVIL ONCE BUT I WONT AGAIN". When someone cheats on someone it can take a devestating toll on us . It can cause illness,loss of weight,even death. The devil knows that we love this person very much and to lose them could destroy us so he comes into our lives with hesatation. Thats what that means. Next,forget it!!! If you let it stay in your mind or your thoughts it will never go away and and it will fester into hatred. Tell yourself it never happened while sub conciecncely you know it did. Go back to the way it used to be between you two. In time it will fade and your trust will come back but NEVER MENTION IT TO HIM AGAIN AND NEVER THROW IT IN HIS FACE because if you do than it would mean you never forgave him to begin with. Good luck!!! My prayers are with you.

It must begin with a true, sincere apology from that someone and a mutual understanding of how/why the trust was broken in the first place.

After that, it is just a long, slow healing process - one day at a time. Be patient, and remember that it will ultimately be up to you to determine if that loyalty has been restored. You will, eventually, need to express your sincere forgiveness.

Personally , I really like it when they fall on their sword. It solves those niggling little doubts. Shows absolute sincerity and ya are guaranteed it won't happen again. Lol
Did you say "AGAIN" as in cheat again? If that is the case then I'm thinking you better face it there will be a third time if you go for the okey doke again. twice and ya help em fall on their sword. Unless it's your twin sister and he gets confused easily I'm thinking he has established there things here,
A. Is a cheater!
B. Is a liar!
C, Has no intention of stopping.
Sorry, Was a bad boy grew up and thats how it is. beleive it or not it's your call.
The only way to keep it from being three times is to stop now!
MnM Good luck.

Dump his dumb ***. Sorry if it seems harsh, but if he cheated on you he will more than likely do it again. Kick his *** to the curb.

First of all you don't have the problem HE does. He was the cheater and it is up to him now to prove to you that he wants to be in a mutually exclusive relationship. I personally don't think it is the best idea to take a man back that has cheated on you as there is all those "what ifs" and I would always be wondering everytime he is late if he was with "her" again. As far as building trust (and with some men this is hard I am finding out.) I always try to be where I tell my guy I am going to be and if I am going to be late I call him. I offered him the pw's to my EP account etc. to show I have nothing to hide. Of course if he had said "yes" I would have dumped his butt for being too controlling lol but I did offer wink wink. It is up to your bf to figure out what it will take to make you feel secure however if you aren't feeling it don't make him jump through the hoops for nothing. Move on to a more trustworthy guy instead.

yaa.. this is difficult question to answer but i think if he is admiting his mistake that he did wrong and then u should forgive him/her if u really love some one .. becoz love is not a selfish relation .. in relation like love.. the main thing is that "truth" if u did not hide any thing from each other then u can trust each other and people who have these kinds of relations must share each and every thing with their beloved them and have the courage to forgive them for their mistakes.. ..

trust urself.. and love urself first...

regards

they cant.

You could make him jump through hoops and maybe eventually think he's tried hard enough. It would be better to communicate, forgive, forget and solve his issue (why he cheated) Honestly all he can do is not f up again. You are the one that has to take the step and trust him, don't get paranoid, don't throw it in his face. The only thing he has the power to do is stay loyal and startcontinue to make good choices (like always returning calls promptly, check in when he'll be late keep his nose clean in general. Only you know if you can trust him after this.

it is very annoying why trust breaks in the first place.
i fail to understand why anyone would be so easy on it and make it happen. anyways. if it is the case, and trust is broken to get it back of course their would be a series of tests. tests not on paper but in action, behavior and love, and if it is passed, i guess as human we should give our beloveds a second or even a third chance. but that is about it!

TO ERROR IS HUMAN...BUT TO FORGIVE IS DIVINE..We are ALL Human and make mistakes. TRUST IS SOMETHING THAT IS EARNED, NOT JUST GIVEN RANDOMLY. If someone has violated your trust for him/her, it will take time, patience love AND WILLINGNESS TO trust again, to rebuild it again. I dont know of any one certain thing, that can be done, to prove that loyalty....BUT IT CAN BE DONE IN TIME.
