Possibly. However it is your house and you call the shots. If you don't want the b/f to stay over (and 4 nights per week does start to look as though he is living there), you are perfectly within your rights to ban him altogether. If your lodger doesn't like it, tough. TBH, unless the boyfriend is paying you for the electricity he uses and gas and the general extra wear and tear he causes, I would say you are being taken for a bit of a mug. Your lodger is a guest in your home and is abusing her position, in my view.
