OK i like a best friend of mine, but i go out with her best friend.... yeah i am lost...?

ok names are my gf is HEY and the one i like is YEH ok:

idk but i doubt it will work after summer and all with HEY (i'm college bound and dont really want it)ok...

well YEH and HEY are close again and so that kinda sucks for me...

i tried once before tell YEH this but it was more of less thru a friend and her comment was he is like family to me...

ok with that said...

I WANT YEH....i have been and am attracted to her...she is such the perfect girl...for me at least...

i see and hear what she goes thru and all... and well... i want to be part of it...

now HEY is head over heals for me and when we broke up first time it crushed her.... and well she still wanted me and i wanted her kinda so we got back together...

ok but what do i do...

YEH is who i want, both makes me happy but YEH makes me more happy or a different type of happy... which i want more...

so yeah i am so confused and lost right know
