You can't force someone to feel something that they don't feel. If he's with her, then that (probably) means he likes her. If he's with your best friend, then you need to lay off him. She's your best friend, right? Would you want her to steal YOUR boyfriend? Friends come first.
Drugs.
you keep going for his best friend and be honest!
Answer:MOVE ON
Forget about it!
Woah! Do not do this! She is your best friend! i think its better if you tried going out with someone else! Else i am afraid you might lose your best friend...
no,you should not because you love him not youre friend so you should stay with him.
you do nothing...just don't be her friend if she's honestly doing that to you!!
beat them up- go bang bang
NEVER! no matter what she says she is going to blab it to the world.
Don't go there! He is going out with your best friend. But then maybe you to belong together as you both are lying to her.
just ruin their relationship and then be there for the boy hahahaha jk
if you realy love your best friend then you really shouldn't be with anyone except him if your using your boyfriend that just isn't fair but before you finish with your boyfriend make sure your feelings for you best friend are real because whilst going out with a best friend can be great the break ups are often harsh
