shit, that sucks man!
but i think you're too young for such long relationships
live life to the max
you'll have time in future for long relationships
enjoy your age now until you can!
i'm 21 too, and i had the mistake to have 2 years long relationship 3 years ago... and i suffered too much for these 2 years... but i don't feel pity now, cause i've learned so much for the love, girls and shit, now i'm stronger
just look forward for your next girlfriend and don't look back
and wtf why you want to marry on 21
you're too young, don't worry, you'll have time for marriage and everything
i hope i won't marry in the near 5-6 years
i poison my life enough alone, i don't need someone else to do it :P
