I haven't been at this for much longer than you, but remember this is a rollercoaster. Nothing she says to anyone can be taken as the complete truth.
You can't let her actions affect you(this much). It will drive you mad.
My eX has gone from - commenting my positive change to - saying she was never happy, that we never got a long and that she thought the very essens of my person was just extremely annoying and always have been. That she had no interest in talking to me and hoped I wouldn't call. This was said out of the blue, just being downright mean. to - being very distant and only down to business and the last weeks now, she has been calling/texting and being nothing but nice and fun to be around. (Now I'm just bracing myself for the continuing rollercoaster I'm sure will follow)
I have done my best to be balanced and not reactive towards her, and have done -fairly- good(I think), yet she has been all over the place. I've been telling myself the same thing I tell you. Try and brush it off, don't go along on the rollercoaster. If I would take it all seriously I would be crushed. Being discouraged is part of this. Be strong, focus on yourself, continue DB'ing for YOU.
