Is it true that men know a woman is "the one" as soon as he lays eyes on her?

I believe it! My dad knew my mom was the one the second he met her. My husband said the second he saw me the thought "i'm going to marry her" popped into his head. He said it was weird as he'd never felt that before or even thought about marriage. I believe he thought it because he acted weirdly. We met on our first day of college. He was the first one there, sitting down and I was the second one in. I don't think it's neccesarily all about looks but something deeper than that. We were together a year before we got married, it is our first marriage. We got married YOUNG- at age 19. We are still married (for 8 years now) and as happily married as I think is possible- lol. We were both college students at the time. He's a computer programmer and I'm a realtor. We both graduated college together.
