There's always been the debate (for instance) about Booth compromising his beliefs and 'dreams'to be with her. Would he father her child if that meant although they were committed they didn't marry? Would it be enough for him if they didn't have a marriage or children and the picket fence scenario? I always have believed that it wouldn't be a compromise for him if he got her. She would be enough.

So, I believe your scenario. He wants more, but in the end he just wants her.
