Friends relationship problems ... should i help?

A friend of mine and his girlfriend have been going out for about three years. Lately her and another guy in our group of friends have been getting ... rather close. She flirts with him and he with her. He has his arm around her a lot...etc my friend is crazy about her and will do anything for her and dosent seem to realize. or dosent want to know. I want to talk to him because he is the one thats going to get really hurt but should i interfere or not? It obvious to quite a few of us whats going on. Either shes bored of him or enjoys the attention she gets from the other guy.I dont want to see my friend getting hurt .. but dont know if i shoud talk to him about it or not...what do you think i should do

If i were u id talk to both of them i belive a story has both sides to it. What if he is doing something wrong you never know.

Cheers

Nothing wrong with harmless flirting and if it doesn't bother him, it shouldn't bother you, if you think it is something serious, talk to both of them.

I'd probably talk to her first see what she says flirting is harmless however this sounds like there is possibly more to it, get her side of the storey think about what she says then decide whether it's worth expressing some concern to him

I don't think it's really any of your business, to be honest. If they have a problem, then they'll deal with it, and if they don't then let them be happy. And just because you see a problem, doesn't mean there is one.

I can understand why you want to protect your friend but like it's been said, if you get yourself involved when the crap hits the fan, all the blame will fall on you and you really don't want that.
If you really must though, bring it up with the girl in a jokey way, like saying something like "You and him are very close, something you want to tell us?" but laugh as you say it or something.
Argh, i dunno, lol. Wait a while and see how it pans out. If she's doing it front of her boyfriend, mayber they know something you don't?

No way, that is a bad idea. You should leave the getting involved and looking like a jackass to a professional like Dr. Phil. Wow I hate that guy. Mmm kay?

I don't think flirting is good,but If it doesn't bother her bf then you should just leave it alone. Cause' if you interfer,then ur friend will get p*ssed at u.and then ur friendship will be over,and all down hill from there.
