Not necessarily.
Looks absolutely aren't everything.
Just because a person is physically attractive doesn't mean they're a good person.
You can be attracted to someone who isn't a good person, and you can also be with someone who isn't good for you to be with.
I don't bunny-hop from one girl to the next, nor do I go entirely based on physical attraction.
Actually, physical attraction to me is nothing more than the initial yes/no question.
After that, if she's actually an amazing person than it doubles down and keeps me bewildered and entranced, but if she ends up being not a good person than my attraction just kind of diminishes and fades with time.
