have you ever been in 'one sided friendships'

[c=003BB2][i]a situation where you put more into the friendship and maintaining it than your so called friend? where as they had the attitude that they could take it or leave it and not bother with the friendship?

i have unfortunately been in friendships like that, back when i was young and naive, but never again, id rather spend the rest of my life alone than have a one sided friendship.[/i][/c]
