You are mine. Mine.

Shame

It's a shame how much he likes her, he puts so much effort into a relationship that just doesn't look right.

He does all the work, and she rides off of him and tries to look pretty by his side.

She's like a trophy wife.
Less than that actually, a trophy girlfriend.

I want to pity him, I want to say it's her loss that she doesn't see what an amazing guy she has.

That's just not the truth though.
In reality, he's just as bad at realizing what he already has.
