I'm a 16 year-old boy and one year ago I met at a party a girl who was one year older then me. Blonde, feminine, nice with a smile that makes the sun look depressed. We talked all the time and I liked her from the first moment I saw her, and I guess she liked me too, because she smiled at me a lot, we were always together and alone, even though her sister and one of the brothers were there. Unfortunately she left 2 weeks after the party, back to USA. Her brother is friend with me on Facebook, but I never met him in reality and he's 20, starting his military career, so I feel scared to ask him and anyway it seems awkward to message him (anyway if you think it's worth the risk, tell me).
I think back at it and I consider myself such a fool that I didn't ask her for her phone number or email. I like her a lot and I don't want to give up on meeting her again, but I don't know what I should do for that to happen. I need some advice!

PS: She doesn't have a Facebook. (I asked her at the party and checked also).

Thank you in advance!

You are both young, and both worlds away from each other. Busy lives, and constantly changing plans for the future. My advice is twofold: continue to think of her as a friend and even a soulmate (although 2 weeks isn't enough time to qualify), not as lost. No one is ever lost because they are in your heart and more importantly, they become part of who you are as you mature.
Second, don't wear yourself out trying to find her, but do keep in touch with her brother on Facebook. Message him privately that you hope you can keep in touch especially because of her (it's OK to be truthful about that!)

I'm 67. Thanks to Facebook, I have connected with people from 50 years ago or more, people I never thought I would hear from again. You are fortunate. As for soulmates, you will have more of them. Don't close your heart to them in some sort of allegiance to her! If she's as sunny as you say, she has tons of friends, and several soulmates, and the odds of her pining away for you are zero, because she would have made sure she had some way to keep in touch.

You're 16. You don't have a clue what a soulmate is yet... much less know who yuors will be. And person of the opposite sex that shows any interest will seem like the greatest thing ever. The good thing is we all learn that the only way to know what a GOOD relationship is , is by having at least a few bad ones. And it takes having several relationships to compare to each other to see what a bad one is as well.

Its also a HUGE waste of time and energy to pursue any relationship with anyone that you can't sit next to or across the table from at a local restaurant.

Its fine to have "friends" online... but its really dumb to pretend to have "long distance relationships" because all that happens is you miss out on real ones you could have had and everything that goes with it including the opportunity to learn from them.

"nice with a smile that makes the sun look depressed." Awwwww so cute. With thoughts and feelings like those you are not going to have a problem with the ladies.

I agree with Joy - don't spend time looking for her. You will only torture yourself and plus you can't be together anyway.

Next time you meet someone don't complete jump in hook, line, and sinker. Let the relationship develop first before you think "this is the one." Love doesn't happen overnight.

You poor young hopeless romantic. Savor your fantasy, but live in reality. I can understand being smitten by chance meetings, and the what ifs that follow. Especially at 16. If you are lucky, this is the first of many such events that will tease your imagination over and over all your life.

Its not a bad thing at all as long as you don't get carried away by those feelings, and lose track of living your life, and missing many fantastic opportunities you will experience. Just keep living. You will know what to do when its really real.

Feels good to dream for a while though I know.
