Crush won't let me buy her a birthday gift?

FYI: I'm 18, she's 17

So I'm basically competing against this other guy my crush is also "Talking" too and she accepted his gift, but when I offered to buy her something she said she didn't want anything because "it makes her feel weird getting gifts from people"

Would you guys/girls say this is a strike against me? Or I'm overthinking it because she's into him at the moment?

Strike against you
Over thinking it
