Am I being a jerk or is GF being selfish?

YOU SHOULD CHECK WITH YOUR DAUGHTER BEFORE YOU MAKE TE PLANS TO DO THINGS. BUT IF SHE SAYS SHE CANT, OR HAS OTHER PLANS THEN YOU ARE FREE TO MAKE YOUR PLANS. DONT SAY I CANT MIGHT BE ABLE TO SEE HER. TELL YOUR DAUGHTER "I WAS CHECKING TO SEE IF WE CAN GET TOGETHER FRIDAY, IF NOT I HAVE OTHER PLANS." IT IS GOOD THAT SHE IS TOP ON YOUR LIST BUT OTHER PEOPLE NEED TO FEEL THEY MATTER ALSO.
