oh, and in usual KD fashion, here's one more thing:
Could you list about five things that your H has complained about you. If he has not, list five that you THINK he might have complaints about you. Even better, ASK your H for five things that he might have complaints about you. That would be a great way to practice listening without giving him feedback. Do not defend his complaints. Just thank him for letting you know and if he wants to know why, just let him know that you are working on yourself to be an even better person than you already are.
Of course, if he gives you ten things... feel free to post all of them here.
