If you could choose would you pick the person that loves you and would do anything in the world for you but you don't love them or the person you love and would do anything in the world for but they don't love you?
Neither ... but it isn't even as simple as that because I have known girls who love me dearly, but are "in love" with another guy ... story of my life actually LOL
I know it is possible to try a relationship with love starting one-sided and sometimes it grows on both sides and you can have a really lovely relationship. But if, after a decent amount of time going out, there isn't that attraction on both sides then you have to give it up and move on. You can stay friends but it's not possible to be more at that moment. Maybe try later when you are older & wiser - if you meet again and are both single.
Love is an outward projection of yourself. It is meant to be given, freely without qualifications or expectations. We're not meant to make people love us. But, we are meant to show our love openly, honestly and humbly. What people actually do is another debate.
This is a very good question. I will give 2 funny nannygoats from life experiences of how others think people think.
A couple are laying outside on the ground just after sex and looking up into the sky when one asks the other "are you thinking what I'm thinking?" It's impossible or just a great coincidence. There is no way they are thinking the same things. No way at all. Often people pretend.
My now ex-wife of 12 years never understood why I wanted a blind in our kitchen fixed to where I could look outside and see where cars are parked. She thought this would have to do with me stopping something I am doing inside because her car had just pulled up. That's wrong. Now that we are divorced I have riveted that blind so it is always easy to see if a car pulls up. Open constantly it's like a peep hole in a door and has only to do with seeing if a car has arrived.
