This is probably about a relationship.

Because you say, don't mean you mean it, Run away to find a home, Happy now, but you don't see it, Run away because you're all alone.

most likely it's a girl who said something that either ended the relationship or put it in such turmoil that she just left, and she had nowhere to go. She was happy to get the whole ordeal off her back, but she's got no place to go.

And you'll never know, what could have been, And you'll never see, where i've been, And you'll never know, what could have been, and you'll never see, where i've been

she'll never know how their relationship could have turned out, or how far it could have gotten. Obviously, she hasn't kept up with her old pal because he must have been getting a lot done since she left.

Because you say, don't mean you mean it, Run away to find a home, Now I'll let you in, yeah, I'll let you in, Yeah.

And she still feels bad about what happened, and he understands. he's willing to give her a second chance if she ever decides to come back.
