I still don't get the whole car thing, all your exchanges regarding the car make it sound like it's hers and you're begging her to make allowances in her busy schedule for the tremendous inconvenience of ferrying you around. But it's your car, right? My attitude would be- "It's supposed to snow tomorrow, so I will be driving my car to work and home, just wanted to let you know so you can coordinate with someone if you need to get somewhere." If she needs YOUR car, then let HER come beg YOU for the honor. Not the other way around. Quit being a doormat.
