I just responded with "Have fun." She'll probably think I'm mad or something. I'm not really, just let down and don't feel good about it. As I said she's never actually cancelled on me, and I don't know any (besides 2 that I met but don't know) of her many coworkers.

Guessing the common thing would be to forget about it, work and focus on myself. Maybe even soft next?

Not really sure where to go from here though, with her. How to act towards her. We hang out every weekend (plans or not) too so don't know if I should tell her I'm busy. Not sure if I should cancel plans we had for Saturday either.

And how whats a good response if she asks if or why I'm mad?

Any practical advice would be appreciated...
