The thought of her posing on the mezzanine in her apartment, while the boyfriend is doing a full days work is GAS!
Surely she'd be helping him out a LOT more with lunch/dinner, groceries and house admin. I can't see her having the initiative of doing any of that without him getting dragged into it so they can do it "together".
Strong vibes they've moved in too soon... she had on her story the other day about how much you learn about somebody when you live together. Personally, when I moved in with my partner there were no surprises, the time was right.
