Is she interested.............?

this girl and i have been talking for like a year. well yesterday sum random girl came up to me and said that she doesnt even like me... i asked her if it was true and she said no and she got really pissed and wanted to fight her. then she asked if i told anyone that we were bf/gf, i said "no lol, but if sum1 asks me i either say not like that or idk." then she told me, "if sum1 asks me i say idk. he's a really sweet guy, but i have to get to know him better." we went to a sports banquet this last saturday, and she brought her mom over to meet me... is she the least bit interested in a relationship? btw she's 20 im 17
