She used me of flirting with her crush when he started it?

so i went to this part where everyone was just having fun. This guy came up and his name was mike. He came with jane. Jane likes mike. Mike does not. He flirted with me all night long and wanted to hang out. Mike started it and approached while I just went along. The next day Jane was talkin **** about me because "I" was flirting with mike and was all walkin me to my dorm. wtf? I hate these chicks..
