Not sure if this is what you’re referring to, but Ani Difranco did a cover version of Bob Dylan’s “Most of the Time” with lyrics very close to those:
Most of the time
I’m halfway content,
Most of the time
I know exactly where I went,
I don’t cheat on myself,
I don’t run and hide,
Hide from the feelings,
that are buried inside,
I don’t compromise
and I don’t pretend,
I don’t even care
if I ever see her again
Most of the time
Don’t know the inspiration, but the theme is similar to 10 cc’s “I’m Not in Love”, i.e. denial of one’s true feelings.
