I'm going to tell my boyfriend to stop refilling my wine glass when he comes over.
Why does he need to stop refilling your glass.
He's too playful and tries to get me drunk sometimes. I want him to be more responsible.
Oh, okay that makes sense. It's your house and not wanting him to do something like refilling your glass is fine. It's fairly normal to establish rules for your own home.
Yes, I tell him the rules of my house.
Yes, I think you'll find that by being forward and upfront is the best thing to do to avoid confusion.
