sad to be alone~

my sis is getting married end of this year or next year...it's my younger sis :(
while i still alone, never have a lover and neither being dated...
i tin it's a revenge as i rejected once before...and now i'm the one being rejected...
why i'm always being ignored? why i'm always best friend of other gals' bf?
am i too bad?or too boyish?or losing my feminism?
and why i always being so insensitive?
why ppl's bf always say ,"u din giv me a chance also, how am i going after u?" but actually they did nothing at all?i just tin that they r just bluffing~
sometimes, felt depressed especially driving back home alone in the dark midnight~
may be i'm destined to be single in my life...
