Quote #1
She had wanted him, in that first instant, wanted him as simply and unreasoningly as she wanted food to eat, horses to ride and a soft bed on which to lay herself. (2.26)
Scarlett's love for Ashley is compared here to wanting food or a soft bed; it's self-indulgence or simple desire, not some sort of deep, timeless emotion. It's probably important here that she's only sixteen—she's not so much in love as she's crushing out. Ashley is her boy band.
Quote #2
"Why don't you say it, you coward! You're afraid to marry me!" (6.181)
Scarlett seems to be more or less correct: Ashley is in fact afraid to marry her. He figures if he married her they'd make each other miserable… but they spend the rest of their lives making each other miserable anyway, so it's not clear what he really gains by being coy.
Quote #3
The thought of this strange boy whom she hadn't really wanted to marry getting into bed with her, when her heart was breaking with an agony of regret at her hasty action and the anguish of losing Ashley forever, was too much to be borne. As he hesitatingly approached the bed she spoke in a hoarse whisper.
"I'll scream out loud if you come near me. I will!" (7.8-9)
Sex and love for Scarlett rarely seem to go together, and neither of them has much to do with marriage. Poor Charles, her husband; maybe he was lucky to die before realizing how much Scarlett dislikes him.
