And her BEST friend is so FINE!!! I like her but I don't know if she likes me. But the other girl likes me and I don't like her! What should I do? So today on AIM (them girl that likes me) messaged me. and she asked me if I like her friend. And I just didn't reply. Look....

HELP! I'm in a circle!! I'm so confused and don't know what to do!?

So the girl on AIM is the one that likes you? Keshia is the one you like? I could have got confused here

So if you like Keisha and not the AIM girl, then say to the AIM girl, sorry didn't get your messages I was on a call in another room and missed your messages. You're pretty cranky when you don't get a reply --- joking like though. Then say yes you do like Keisha. Be honest and confident.

If I've got it wrong and it' the girl on AIM you like then tell her the whole in another room story, also the pretty cranky part jokingly and say that no you don't like Keisha not my type but you are my type.

Whether you're 13 or 70, girls like confidence in guy, learn this from the beginning, confidence and honesty and you'll be fine. Don't start being their little chew toy in this circle, if they start giving you hassles and you feel they're just playing around with you, don't give in just completely ignore them and be your own man. Don't be horrible though
