I thought Love Means Never Having to Say You're Sorry!
(how many of you remember that "sorry" line?)
I think LaTeeDa is right--if you truly detach, apologies might be nice, but not necessary, IMHO. I wouldn't want to waste my life energy waiting for an apology--that's in the RA's court, not mine.
My AH messes up and sometimes apologizes, sometimes doesn't. I don't expect an apology, and I don't wait for one, and I don't get mad if I don't get one. I just go on my merry way.
One time some friends of mine went with their church group to bring gifts to poor people in town for Christmas. When they came back they complained that "they never even said thank you!" Well, I wanted to ask, is that why you went? To be validated with their gratitude? I thought you went simply to give them gifts. We can't look into the hearts of other people--sometimes remorse is there/gratitude is there, but hard to express for whatever reason.
