im soooooooooooooooooo confused

ok so i thought this guy liked me and we were gonna be set up by our friends but we havent gotten a chance to yet and i added him as a friend on facebook and when i did it said he was single and then the other day i asked him to come to my schools talent show on the 22nd and he said he will if he can but he is grounded but he is gonna try on that very same day i was on his page because i was bored and it said he is in a relationship but it doesnt say w/ who and now i think he is avoiding me :/
