My lodger has a boyfriend who usually stays over one night in the week. He’s quite nice and cleans my kitchen when they’ve cooked, which isn’t bad.
However I left for work late today and realised what they do when he stays is she posts her keys through the door and he puts them under the bin, I assumed they live together. House is set back from the road and you wouldn’t get pedestrians knocking it etc but I still live in a big/bustling city... aibu to not be happy with this arrangement?
