Why does she get so offended?

I think that she really loves you and really want you back.

My advice? Follow your heart. If you suddenly change your mind, go for it. I don't think that your heart makes mistakes.

You guys broke it off but she still wants to go back, that's clear. That is the reason why she staid friends in the first place; hope. It is her problem and she won't do anything to you (or have anything done) Don't worry about it, if she keeps acting strange then slowly build the friendship down.

She got offended because she is making this all about her. And I would watch yourself because she did make a threat to you. When anyone takes anything personal it is because they think it's all about them. Being humble is not an easy tasks and most everyone takes things personally. It's just that some people are better at not taking things personal. It takes a lot of humility to not take things personal. Just think of it this way it's her "stuff" not yours. Be careful. And I hope this helps.

When someone is vulnerable and puts themselves out there like that, Rejection really is like a huge slap in the face..

She puts herself out there and gets burned, so she is snapping back to defend her ego..

wow sounds like a *****. If she attractive probable cant stand rejection. Be nice to her still and if she plotting something it will make her feel guilty because your being so nice.

you turned her down..... she was probably nervous about it, you turned her down and she got bitchy about it.
