"I got this feeling on the summer day when you were gone" "I threw your shit into a bag and pushed it down the stairs"

sounds to me like she's been left by someone she lived with. It is her place, so she can throw his stuff out. This rules out parents in my opinion.

"You're on a different road, I'm in the milky way You want me down on earth, but I am up in space You're so damn hard to please, we gotta kill this switch You're from the 70's, but I'm a 90's bitch"

She has been in love with an older man, who is settled and down-to-earth and she feels she cannot meet his standards.

"I crashed my car into the bridge, I watched, I let it burn" "I don't care"

This is an act of liberation from the standards of her lover. The car seems to symbolize these standards, perhaps bought with his money? Or is it wealth and security she abdicates from?
