I like your observations, JulieRB -- it does sound like one of the ickier romance fantasies (the kind that give the genre a bad name). Wave a magic wand and the ugly beast turns into a well-mannered prince, indeed. Oh -- and all the woman has to do, to bring about this fabulous transformation, is cater to him and flatter him and let herself be humiliated repeatedly. That's all (!).
Bush having a contrasting personality (much more reckless and irresponsible), as well being a mix of the exotic (wealthy family, went to Ivy League schools) and familiar (apparently they had actually been at the same elementary school as kids), might have provided some excitement. Although I wonder how things might have turned out, if he'd had to compete with any other suitor who had half a brain, and who respected Laura and shared many of the same interests.
Re: the urge to teach or "reform" him, I guess that would have been another factor as well. I would have hoped that by the time she got together with him (I think she was in her 30s), she would have been wise enough to know that the odds are against being able to "reform" someone who is that set in his ways. About as much a chance of that, as getting him to love school and enjoy literature! Most people who are so inclined find out pretty soon (firsthand or by observation) what it's really like (and indeed, I faced something like this when I was in my teens and twenties) -- and if they're lucky, they don't end up stuck with the guy.
But someone I know, in her 40s with a pretty practical view of life, recently decided that she was going to try to "improve" a new boyfriend, so it's quite possible that Laura also got carried away with enthusiasm. Certainly the incident when she challenged him over his drinking (and he just stood there smirking at her, and pouring himself another drink) would have thrown cold water over that particular fantasy.

In fact, his friends saw him as a bit of a reclamation case, a tad eccentric and a slob. The wives of his friends took pity on him and did his laundry.
"I didn't think he was really shopping around," said Joe O'Neill. "He was at the age where it was getting awkward to be a bachelor, but I don't think he thought about it." Bush, he recalled with a laugh, "wasn't exactly presidential timber yet. It took some coaching for us to get the girls to go out with him."
