Would I be going to far?

This girl is the best thing that has happened to me in my entire life, I think she must like me as she has said so on our dates and tells me she has a better time with me than she has had with anyone else. This is why I cannot understand her sudden change of heart.(literally overnight) We went from telling eachother everything about ourselves to i'm not interested in one day. Is she scared of something? Would I be crossing the line if I sent her some flowers to let her know that I really do care for her? Or will that only scare her away more, which I do not want to do because I would really miss being with her.

Would I be going to far?
talk to her before anything else, if she really likes yous she will make that crystal clear to you. then, just to be sweet send her the flowers. but if you talk to her and you still cant read her, maybe step away from her a little bit and see her reaction. dont get too attached
Reply:Maybe one of the things you told her about yourself you should have kept to yourself. Look, you're being played. There are plenty of fish in the sea , quit wasting time on this one.
Reply:Definitely send the flowers with a message attached asking her to please tell you what went wrong. If that doesn't work, then I'm sorry for your heart break.
Reply:some girls would love it and then some girls it would scare her away. i would talk to her first and see why she backed away all of a sudden. what did you do or say the night before? did you try to kiss her or hug her or even just hold her hand? if so then she might just not be ready for whatever you did the night before.
Reply:Tell her you don't want this to end. Most girls wish so much for someone who actually gives a crap. If you go to the length (Flowers, songs, ect.), she'll know how far you're willing to go. How much you'll miss her. How much you care. Take the risk.
Reply:Send the flowers and if she rejects them leave her alone as someone else could have come into her life
