I've Heard lyrics

I heard this I heard that What do i believe? It's hard to give It's hard to get And once you've lost it it's always gone I know i shouldn't accept One person's word as truth Without at least Giving you the benefit of the doubt I get so mixed up By the things you say And the way you act Too many times This has happened before I always thought the wrong thing I never gave you a second chance Now it's happening all over again
