well, kitty, could it possibly a growth action for you TO tell him that you felt what he did was unkind?
being someone who has let other people kinda step on me all my life (my first vivid memory of this was when i was around 13), because i was too damm scared to stick up for myself, i would hope that i could get up the guts to say something like:
"um, i guess i thought that we had made a plan to do something over the weekend. it's not that i'm mad.... i guess i would just rather have people in my life that do what they say they're going to. i spose i felt a little disrespected. i do care for you; i wish you the best."
