Would you make yourself readily available to a girl that keeps breaking dates with you?

Absolutely not! You shouldn't make yourself readily available to her because she won't respect you for it (you are a push over and she knows it) and she's extremely rude and thoughtless doing this to you over and over again. Tell her to take a hike! You can do much better. Girls that love the guy they are interested in wouldn't do this. Take control of your own life and leave this gal behind in the dust. Considering there are well over three times more women in the world you should feel like a kid in a candy shop!
