Hmmm... So our h decided that she couldn't marry her fiance, only she decided it in the middle of the wedding. She bailed, then leaped through the H's truck window.
Got that. Got that she realized the sort of man the H was and tried to avoid getting involved. Got that he didn't like being told "no" so pursued vigorously. Got that she caved. Got that, having gotten what he wanted, when it was convenient for him to bail, he took off. Even got that eventual HEA.
But getting all that doesn't mean I like the H for a H, mostly because I have a hard time believing he'd change that much.
