GGB, Yes I am trying very hard today to not be sarcastic with him. It is a defense mechanism and not even a very good one at that.
Being REAL with him has a much more profound effect. After all, he loves me and does not want me to be hurt by his actions. When I respond with sarcasm, it just pisses him off and he doesn't care what I think. When I respond with my true feelings he is forced to reflect upon his own actions or inactions.
Btw, I don't always react with sarcasm when he compliments me. Mostly I just say thank you. That way, whatever he was getting at (inner/outer beauty, whatEVER) I am covered. Or I say, "What do you mean?" and try to fish for more compliments.
I'm an idiot, I know. Take whatever I say here with a big container of salt.
