'And if I dress like a slob? That's ok too?'
^^^ Of course, if that's what you want to do.
Never change my clothes, never try to look nice for my partner?
^^^ Again, yes, if that's what you want to do.
You're supposed to dress for yourself and your own comfort, not for someone else. The man hostage gets dressed everday (in casual clothes), on days I don't have to go anywhere, you'll be hard pressed to get me out of my PJ, slips and dressing gown. I think out of the two of us, I'm probably the more scruffy on 'off' days.
