Did I hurt her?

okay so got myself in a sticky situation here. I'm friends with benefits's with this girl, and it was in our agreement no commitment etc. I told her that I liked our mutual friend, and then she got kinda weird about it and went from being supportive to saying its weird and doesn't like it. she said only reason doesn't like is bc that girls her friend so will be awkward. and we were decently close but few days after told her she's been ignoring me, bumped into her at school and she said she's going through bad time. after that, she ignored my messages even when I asked her if she was doing better. am I overthinking, or is it possible I somehow hurt her?
