What do you think I should do?

tell her your feelings but dont get your hopes up. remember youve never met her and things might be different later on.. youre only 16 and have enough time to fall in live again. i think this is really cute and sweet but you also have to think that there will be a heartbreak. im sorry if im harsh but nothing lasts forever. and yea be happy with her for as long as you can but expect a heartbreak.. take care and i wish you luck :)
