No.
For me, infatuation has less to do with personality and more with appearance...for example, in my tween years I was infatuated with Keanu Reeves. Not because of his acting or because I thought his interviews showed an interesting person. I just thought he was pretty and had a huge crush on him. (I'm not usually one to get infatuated with actors, though).
I form real relationships -- the kind that last past infatuation -- based on personality. I met my husband in a MMORPG and had no idea what he looked like for ages. When he did send me a photo, I didn't think he was that attractive! He was interesting, smart, funny, and warm; those were the initial qualities I liked. (And when we met, he looked a lot better than he did in the picture he'd sent.)
There are a lot of people I find interesting here, who's posts I like to read for a variety of reasons. No infatuation though. I'm not surpised, though...the only person I am attracted to is my husband. It's been that way for a long time now! (I know that's unusual, but that's how I am.)
