yes, it may not seem like it but that's true... As for those who think she likes (crushes on) Shadow, it seems that is false, but they are friends.
My answer: It depends what 'sonic universe' you are refering to.
In the games, it is still unanswered, she might or might not.
In Archie's 'Sonic the Hedgehog' comics, no. She only flirts with him to gain what she wants, as she does with all men she wants something from.
