what will you do if you knew person you love is flirting with your best friend

I will angry so much. Cos if decide to make relationship with someone that is am really serious with this relationship(i will loyal to him, honest) and i want same think from him. i can't tolerant he doing like that to me and i will be frankly told to him what he doing is already hurt my feeling and i don't like that.

Honestly, if your loved one is flirting with your best friend then you dont need to take it. If your best friend is flirting back, then there is a problem. Talk to each of them alone and explaine to them how you feel. Tell them each that what they are doing is wrong and that if your bf/gf likes your friend then they should have broken if off and started dating the other person. Tell your best friend that what they are doing is hurtful and is really eating you up on the inside. That you call them your best friend for a reason, but they are betraying that trust. Then find out if they have feelings for your guy/girl. If they both have feelings then tell them good luck and to not contact you ever again. Then go out parting and forget the whole thing. Nobody should cause you that many problems. Maybe you'll find a person who wont do that kind of crap to you and loves you and only you.

I'll talk to her and tell her if she wants to flirt with my best friend well its better for us to go on our separate ways. and girls like that cant be trusted and for me i really got turn off.

kick his A S S!!!

i'd quietly pull myself away

i will leave her..confirm!!!!!

catch them in the act. then dump him. and dump ur best friend too. let them be together if they like themselves that much. maybe they deserve each other.

I would kill him...

i think i will try to accept that, because if there is someone i like then i just like to see her happy and have the best thing, and with my best friend i think that's the best thing she can ever get, because there is some reason i call him best friend, u c what i mean? and i guess i'll just move on, and congratulate them, and stil be friend with them, and try to find another nice girl to be loved.. i think that's some sort of happy ending, and live happily ever after.. which is very nice.. hehehe

Well they would not be my new love no more because I would finish it and if my friend was flirting back, she'd be no longer my friend, aswell.

This situation, you need to know that whether you are the bf/gf of the person. If my bf is flirting with other girls, I maybe angry but I will tell him the truth that I don't like the way he is.

Confront the guy. Then confront your best friend. Then if you confirm that it is true, leave them both. You don't deserve people who are going to do that behind your back.
