You could've done everything perfect, textbook DB, and this day still might have come. If she had so many people telling her why she felt the way she did - she was probably looking, at least on a subconscious level, to prove to them they were wrong and she was right.
If you had been enthusiastic about being friends, she may well have said 'see, you don't love me anymore, this is for the best'. My point is, you handled things pretty well. Yes, you were shocked, who wouldn't be - I've been there and have the t-shirt. But try not to read more into than what you actually know for a fact (and remember the believe none of what you hear and only 50% of what you see rule).
Your sitch is still pretty new in the grand scheme. But for your sake, and your girls, keep DB'ing. It's helped me get thru a lot in the past few weeks.
