Hey. I'm sorry you are in this situation but as I look at it you can either bitch about it or make it work the way you would like it to work. Seem easy in words yet I know it's harder but what else can you do?!
It's hard to make friendships and sometimes it takes ages but don't give up. Focus on being more open and try to build a friendship with people who you think accept you as you are and that you like to be around. Don't come on with the attitude of being lonely and friendless because believe it or not people sense that vibes and they're not all that friendly. Rome wasn't build in a day and certainly a relationship of trust, care, love, etc - between two people takes perseverance. You are not the only one on boarding school who probably feels out of place! Maybe the other kids are feeling the same but nobody talks about it. Most of you are in that vulnerable place but that could bring you together.
Be patient, understanding, compromise, listen... Just be yourself and soon you'll find a friend! - life is about this! soon you'll go to college/university and start it all over again! but the important thing is that you learn to not let go and keep trying! Catch your breath, pick your moments and don't life slide right by you.
The pain you have is understanding! but I'd advise to take it and make yourself stronger. What doesn't kill you makes you stronger, right? - Do that. Face your fears and see what's beneficial to you! This type of situations are really important because you determine and learn valuable skills, lessons, paths, things, etc; that you'll always need in your life. Think straight and be smart. What type of life do you want? What type of person do you want to be? How can you make it happen?
Your parents are probably just trying to give you what they think it's best. It might not seem like it to you though, but that doesn't seem like they hate you or want to hurt you. Perhaps communication is missing and you need to express them what's going on in that head of yours. Risk some things and see what you can get. Talk to them, would you? - Is the best thing you can do if you really think that boarding school isn't working for you (although if you think about it... You'll go to a new school again and start all over. Friendships and all.. Is that what you want? or can you make what you got work?) and if you want to work things with them out. Give it a try.
I think that you need to build up some self esteem and respect in order to be happier. It's obvious that you are not in a good place with yourself if you are putting yourself in a situation like that with that guy. You know that he doesn't want anything with you and that realistically you are wasting your life. Stop waiting for him and all those things he'll never do for you. He doesn't like you, well too bad. Get over it and find yourself a better place. I'm sure that once you start improving you'll find somebody new who will love you back but for now learn to love yourself.
Life is hard but there's always something more. We experience bad times to appreciate the good ones so just hang in there. You know this deep down! The life you want is waiting somewhere around here but you just need to find it and make it happen.
Good Luck!
