I've stuck in a complicated break-up. Any idea how to cope whit it?

I don't believe you lost her over this ''no '' thing...I honesly believe that she likes you but that she had no romantic feelings for you. You will need time to get over this emotional hurt but it has happened to most of us that we met someone and the relationship ended..or we were left..I am sure she liked you but there was no real pion there and you should focus on other things now if possible..socialize, go and meet friends..study. Don't start a new relationship with any girl right away because you are on the rebound..once you get over the hurt, which is normal and this can take time...let it run it's course, you may feel angry for a while, that, too is normal, then will come a time when you accept that it's over and your relationship with this girl could not work out because she was not willing to talk to you about problems and it's very important apart from ''a mutual spark of attraction to have mutual respect and mutual trust..and also to be able to communicate with each other and talk to each other about anything and everything...she was not willing to discuss this with you..in a relationship where you feel that the love is mutual you will find and want a partner who feels she can talk to you about anything and where both of you can share hopes, dreams, fears, talk about problems...and find a solution together..she already had her mind made up for herself that she wanted another guy...accept it even if it hurts, you will get over it and you will meet your soulmate one day..it happens to most of us, this situation you are in right now to get dumped..is not nice at all but you become more mature and you take your time right now and focus on other things..then in your next relationship you look for the complete package...where you can talk to the girl you care about about anything and everything...that is also the only way to keep a relationship happy. If a married couple or any couple can't communicate with each other anymore and if only one is interested in making it work, then that's not possible..it takes trust and communication and it takes two people who want the same thing out of a relationship and work on it together as a team..she did not want to do that so you have to let her go...don't hope too long that she will come back..I am sure she did not leave you because of the ...She seems to still like you as a friend..there just was never any pion..never any spark there in your relationship...I don't believe it takes the ual act to find if one has this mutual pion or spark for each other...in your case you had it for her, she just cares for you as a friend and unless you can accept to just be her friend and that she has no deeper feelings for her, you need to let her go or else accept her just as a pal...and know that love is out there for you somewhere else with somebody else...whom you will meet if you give it time...x
