I don't know why, but I feel like something is changing in her...I was even reluctant to say that out loud - and I may very well be wrong...but there's something different going on that I can quite put my finger on...maybe it's just me that's changing...and I'm making the mistake of thinking it's her...I think it's just that I've been able to be very friendly with her lately - no matter how she's acting...maybe it's just that it makes me feel good, and that's the change I'm feeling...
It could be that you are getting much better at not "taking on" her anger and responding in kind to her provocation. If she has noticed, (and I'll bet she has) that she no longer has the power to control your feelings, she will probably change in some way too. I'll bet she senses your quiet, gentle, strength.
