Most Helpful Girl
I agree with SuperPerve in regards to your friend. If she knew you were into the guy, then I would definitely be mad. If she had no idea, then probably not. You might be mad in general at the situation, but don't be mad at her. In all reality, if you liked a guy and were not aware that any of your friends like him, you'd probably hook up with him too.
As to the guy, it also depends. Are you guys serious about each other? Because if he is single and has no commitment to you, then you shouldn't be mad. BUT, that being said, I would probably not go after him anymore. If he was interested in you as more than a hookup, he would not go around hooking up with other girls. So if that's the case, don't be mad at him, but just let go of him and find someone better who is only going to be after you. Good luck!0THIS IS NOT RELEVANT ANYMORE
