What Do You Think Happened?

well....i like this girl and the only people who know, i think, is this girl who i was really good friends with until she moved and another one of my "girlfriends." i told them not to tell any one else and i believe they didnt. But someway or somehow, a lot more people might know. The other day i was at a pool with my friend and she (the girl i like) showed up with another friend. Us 4 were talking in the pool and everyone but me has a girlfriend or boyfriend ( ): ) so they went like hows your bf and gf and that stuff and they said to me hows my imangry gf and i said she was goergous then i went under the water and my friend told me that when i was under the girl that i liked friend turned to her and said that she was gorgous. So.. they ovisly know that i like her. and also before i even told the other girls that i liked her, me and one one my friends were talking and i said wheres MY girlfriend and he pointed at her so he knows too. And i dont know why because we dont really talk at all and when we do its short and terse. So what do you think happened?
