what if she invite me to hangout this week should i say yes even i already have plan on that day to my friends?(i can cancel that plan just to hangout with her cuz i know my friend would understand me)

Question is this is count as a "to much available" for her cuz everytime she invite me i always say yes and cancel all my plan just to be with her. She would lose interest if I'm always available when she invite me or when she want to spend time with me?
