Hey! I saw your question to the MOD on "My already-taken crush likes me!!". I wasn't sure if she had the answer you were looking for, so here's a second opinion (: First of all, you are not in any way betraying your BGF and he shouldn't make you feel guilty since you guys weren't actually "DATING". Labels are stupid, but sometimes you need them just to be clear. I wouldn't tell him about you liking his best friend unless he flat out asks, because when you see it as betraying his heart he might not like that his two best friends are into each other. He's probably still missing home, and hearing that he will be the third wheel every time he visits will hurt a little. If he point blank asks you "Do you like *so and so*" or "Who do you like?" I wouldn't bring it up in casual conversation! Hope this helps! If you need any more advice, check out my profile and drop me a comment. Kisses!! ~Katie
