Hey, I've been there. My ex wasn't particularly 'bossy' or anything before she left, but man, after she left . . . Once I realized she wasn't kidding, I got led around like a bull with a ring in his nose for awhile. I was either kissing her butt and cooperating to a fault or trying to "make my case" . . . which she didn't care whether I made it or not. Not much good in making a point when they don't really care if you do or not. Keep plugging away, man.
Life may be short, but . . . well . . . it actually IS short, now that I think about it . . . . particularly when compared to planetary formation and stuff.
