Sorry - haven't watched for a while until this week but are these two together?!

They are, yes

If Diane and Doug married, that would mean she would have Laurel as a family member again

I want them married.

Again?

Sort of. Laurel was married to her ex son-in-law and is the daughter of her current boyfriend. Can't think of anything else.

I like Diane and I like Doug but they somehow don't 'fit' together for me.
