Falling in love?

How does one fall in love with someone, when the feeling isn't mutual and that person cant accept a friendship and they would rather not have anything else to do with that person ever again. is it because they know that they will never have the relationship that they really want? or did they really fall in love with that person and its just too painful?

To be honest, I've never understood falling in love. I've always thought it was bs, frankly. I made a decision to date everyone I dated... granted, it was usually a VERY stupid decision... but I didn't just "fall" into anything like a silly little victim. I chose my mistakes, for better or worse.

Maybe sometimes people "fall in love" with people that can't realistically be with so they can keep themselves from being in danger of getting hurt in an actual relationship. Maybe they fill their heads with hopeless fantasies to distract themselves from the loneliness they feel. It's hard to say. It's probably different for every person and every unrequited love.

It's very uncomfortable working or hanging out with someone when you know they have romantic or sexual feelings for you and you don't feel the same way toward them. You have to constantly watch what you do and say to make sure you don't give them false hopes. Once that becomes the situation, it's a hassle some of us would rather not deal with. The best way for to avoid it is never consider someone "a person of interest" unless they show signs they feel the same toward you. It's always much easier to deal with what is than what might be.
