Should I tell my friend about this?

i definitely think you should tell your friend. he has a right to know. I mean if that's your friend, you would think he would do the same for you, so why not for it for him this time? You wouldn't want him to keep this information away from you, so why keep it from him? Also when people are wrong, they should be faced with the consequences, so don't worry about getting involved. They should have never did it. And telling him, would probably make you guys into better friends, because he feels that, you have his back, no matter what.

Do what you think is the best. If you want to tell your friend about what you saw, for sure your friend needs proof beacuse your friend wouldn't believe you. And if you dont want to tell your friend that's your decision but make sure you can handle your conscience because it might hunt you for not saying it... Either way you are involved. If you tell you are really involve but if you not tell, your conscience might hunt you...

How close between you and your friend? if you both are really close then you can ask your friend about his relationship between him and his girlfriend. If he opens for you then you can open a little for him too. If he just dont say anything, then you are better not say anything back to him. sometimes his relationship is complicate to understand... she might try to date someone else to get some fresh air or she wants to give herself a little time about this. who know, you should show up when you see her. just to see how she reacts

I once heard that in this kind of situation, it is best not to get involved. Thinking of it, I am somewhat torn in between. I also like to tell a friend if that situation arises to me too. However, by doing so, am I making it worse to them or it is fine to do so? What if we are judging it in a shallow way? In your presented scenario, there is no further contact like kissing so I wonder if they are just friends on a reunion or so.

You definitely should tell your friend about it. But make it sure first that there something between the guy and the girl. Case maybe, the girl needs someone to accompany her but her boyfriend was too busy to do so, so she resorted to someone else.Just tell your friend with care. Tell exactly what you saw and don't give malicious comment. Just let him do the rest.

You would have to make that decision for yourself. If you were in your friend's position, think about whether YOU would want your friend to tell you what is going on. Personally, anything that can hurt my friend, she/he has a right to know about to spare him/her of any further heartache or embarassment.

You should tell your friend about her girlfriend dating another man. Dating or not, your friend must know. He has all the right because they had a relationship and it is all wrong when she do that with out telling his boyfriend about it.

I hope you could keep silent. Everyone has his or her own space, even boy or girl friends. If they are not partners anymore, they know how to solve it. Your report may lead them to determine early.

I think you should not say anything to him right now. You need to fine out more about who the guy she was with before you say anything to your friend. Who knows maybe your friend already knows his girlfriends was out at the club with friends. Maybe your friend was at the club but you did not see him and she was just dancing with a friend of theirs. Until you fine out more about what was really going on you need to just stay on the side line.

I think you should probably leave it alone. Chances are he already knows what she's up, if he doesn't he'll find out soon. In the mean time he's going to need a friend to help him through. I'd just let him find out on his own, or she'll accuse you of orchestrating the situation. You'll loose your friend forever.

Tell him. I don't see anything wrong with it. If the other party is not guilty of two-timing your friend then it shouldn't be a big deal. Just tell your friend that you saw her gf out on the same club with someone. I'm sure you would want your friend to do the same if you were in his position.

i strong suggest that you tell your close friend,maybe he will beak his heart,but mental injury is better than being his girlfriend cheating,do you agree? and if you dont tell the truth,i think you are like his girlfriend,you are cheating him too,it will be more painful.on the other hand ,maybe there is nothing relations between his girlfriend and the guy.

It can not hurt to bring it up and let your friend know you saw his gf at a club with someone else. It may turn out to be nothing and you are reading far too into it. But, it may turn out that you uncovered a can of worms and are bringing your friend up to speed on what is going on. Either way, you are doing what a good friend should do...tell the truth to friends.

No, I think you should leave it alone. You don't know the real story behind what you saw. Jumping to conclusions may destroy their relationship as well as your friendship to that girl's boyfriend.

I would ask him " Where were you the other night. I saw (her name) at the club but didn't see you. That way he knows she was there with out you accussing her of anything but he will start asking her questions and hopefuly will find out on his own.

This is a tricky situation. I think that before you tell your friend, you should give the girlfriend the benefit of the doubt and ask her about it. If what she says doesn't jive or if you think she is lying to you, thats when you should think about going to your friend. You do have to be prepared though, because your friend might not take it well and it might cause problems between you. (If you are close friends, this should not happen.)

I think that you should keep this as a secret first. Try to gather more information on that girl and the guy she was with. Maybe you just misunderstood and maybe it was her long lost friend or cousin perhaps. I believe you should investigate first if you are really trying to help out your friend. Maybe your friend knows about this the whole time. Try to ask. But for me. I don't think I like to interrupt in such situations. I don't want to be involve. The guy would appreciate it if you go involve, but the girl might not. So, much better if you keep it to yourself and wait how their relationship would end. Not all secrets can be kept forever you know.

why not try to tell your friend anonymously.give him some hint of what his girlfriend is doing behind his back.maybe by that, you have done your share and leave your friend discover for himself how his girlfriend cheating on him.and you have been loyal and extend your concern to your friend even without directly involving yourself to their problem.

i would be brave enough to tell my friend about it, just the facts and without additional comments or exaggeration. it is up for him how to take the news then.

If they have been going out for a long time then you should definitely tell your friend but if they are only casual and have only just started dating then you should let it run its course because you saw her do nothing and telling him may be silly because she could have been there with a friend and you telling your friend will start all kinds of drama. You should have simply gone up to her yourself that evening and asked her straight forward blunt honesty always goes best.
