Cover art for For You lyrics by Barenaked Ladies

I don't think it's that he doesn't think he's good enough, exactly. I think he can't open himself up enough to really be participating fully in the relationship.

In fact, it's not just the relationship: I think "If I hide myself wherever I go, am I ever really there?" means that he's missing out on his whole life, never really being part of anything, because he's too scared to open up to people.
