hmm, you said it right there, relationship... It doesn't matter if one person gives all they can, if the are the only ones showing and giving its as doomed as the titanic i'm afraid.
I know what it's liked and trust me I've been there and it really hurt me, I'll let you in on it but I was going to go out with a girl who was a friend and we both liked each other this was when I was younger and I count this as the first time I told a girl I liked her.
So we arranged to go on a date (my first) and I got completely stood up. Anyway this isn't the point of the story but I swallowed my pride only to be stood up another 5 times! Yeah I gave up a lot of feelings and hope to do this and it really hurt, esspecially as we were good friends before. Trust me giving up things to be with somebody really doesn't work and i've learned it the hard way, you gotta play tougher, and I know it's not easy because it isn't my style either.
I have ignored the bitch ever since.
