Nothing gives anyone -- not boyfriend, old buddy, neighbor, your sister -- the right to exploit you for personal gain. If you detect that someone is deliberately attempting to take advantage of you, do not remain tight-lipped -- stand up for yourself! Approach the individual in a tactful manner and ask when he or she would be available to have a conversation in private. Hopefully, doing so will defuse the situation.

Unfortunately, however, I never had the guts to ask her to be my girlfriend. Still, she could have hooked up with anyone who wasn't my friend, let alone my closest buddy. I don't know if it was payback for giving her false hope, or whether she did it in hope...
