AHHH i feel like an idiot, but should i??? im just confused.... please help.?

okay so i went skating with a few of my friends. and we found this really really hot guy, so we asked for his number. and of course we got. and that happened friday night. i talked to him saturday a little bit, and same with my other friend mimi, and then my other friend marie talked to him the entire day. on sunday, i didnt say anything to him, and neither did kaley, once again, missy talked to him for a good amount of the day. and today, monday, i found out he has a girlfriend. i was hurt, but not so much because its not like we were ever going to get married. and we decided to still be friends and everything. so just about 15 minutes ago or so my friend kaley calls me. (just to let you know, my friend may helps mental ppl all around where i live from different schools) mimi tells me that she talked to may about him and she said he has mental problems. we really felt kinda idiotic there. then my friend dominic texts me. and this boy tells his entire hockey team (half of them are in my grade and go to my school) that we were all over him and he showed them all the texts we sent him. and i did flirt, and so did mimi, and marie did a lot too. me and mimi dont want much to do with him at this point. and we were never all over him. neither of us went to school today because we are both sick. neither of us want to go tomorrow because we have a feeling we are going to get made fun of for everything we said. marie doesnt know because her phone is off and i have no way to contact her. so should i be ashamed? i dont know. what do me and mimi do tomorrow. advise is nice :) thanks
