Don't know what to do?

There's this girl
but I don't know what to do, she's got a boyfriend
but want's me to.

We're alway's together
And it's hard,
To play and mate
When she's the other card.

I wanted more one night,
And we both said
It wouldn't be right.

What do I do?
Make a move?
Or just handle
How to loose?

I don't want to get involved,
And leave thing's unsolved.

You can't help your feeling's,
Just leave them to the dealing's.

I'm going to leave it be,
He's lucky to have her
Don't ever set her free.
