Of course you get along great...and she's holding that hostage to ignore you on the issue you want addressed. As soon as you say something, out goes peace and tranquility.
My FRiend, this is what a temper tantrum looks like when thrown by an adult. She doesn't want to deal with it "for your sake" and doesn't want to admit her own selfishness, so she makes it impossible for you to approach the subject.
Problem solved...for her.
My husband sure looks great to me after reading some of these posts. (Of course, he looks great to me anyway, and says I look great to him--no problem in that area after all these years!)
