I'd just call her and tell her that I'm coming from a long way away, so are you sure you're gonna be there?
I've had women "waste my gas" and I tell/text them you just wasted $30 in fuel (b!tch!). One onetime responded that "wtf do you drive a POS 9 gallon/mile sh!t car??" mocking me for being upset, belittling me for her own fvcking flaking. Women can be out and out god damned CRUEL and vicious as they think they can do NO wrong - TOO many guys sucking their as5 everywhere they step, everywhere they go. What guy would buy a $50,000 wallet? Women seek to upgrade their stupid as5 handbag to the tune of 50k if they could see Reese Whitherspoon (upsetting PETA by buying a $50K python-made purse).
Women don't care about you, your loss, your expression of disappointment. They think that you should just be the male and have NO emotion no matter what, and they WILL walk all over you and spread abject LIES to their/your friends with no conscience whatsoever. This goes for 93% of women. They just don't give a fvck. They're weak, spineless, most of em.
