confused...on love....

Is it really possible for someone to fall out of love??
what is love anyways....... thats the million dollar question!!!

How can one person say they love someone then have feelings for another??Some people say love is a feeling. the whole butterflys in your stomach, cant keeps my eyes off him love!! others say its a choice! how can you choose to love someone. a choice....... you make millions of choices a year.... but you pick one person you choose to love??? how is that possible? or how some people say you will just know when your in love..... okkkkk how can you know and choose to love the person at the same time!
How do you know who mr. or mrs. right is??? becuase in every relationship ppl seem to think oh this is the right guy he treats me perfect but then a few months or years down the road he either treats you like crap or the chemisty just dies!!!

why is it so hard to find something everyones looking for?? the people who want it cant find it and others that have it and just walk away. why does everything have to be so complicated sometimes! why cant that one person just walk up to you and say im the love of your life and then get hitched! why is it such a long and hard journey!

I know everyone makes mistakes in life about love or lust or whatever it is! but everything happens for a reason. whether its breaking someones heart or just ending something that just isnt working out! that person knows what is best for themselves! and if it is meant to be then it will no matter what! in the end life unfolds eventually.

please tell me your opinion on everything! about love relationships i wanna hear it!either its your experiences or just random thoughts on the whole thing..... anyways thanks for listening!
