How is this even a problem? Do you like one of them or are you possessive of all your friends?
If you can't talk it out with your boy...Dump his ***. Dont let anyone make you feel Like ****. Especially a boy. Also unfriend that friend.
Ok hope it all goes well for you then.
1) Unless you hack either of their accounts (DON'T DO THAT) or ask either of them (DO THAT INSTEAD), you'll never know.<br />
2) What does it matter that they talk?
