I can completely understand how creepy and unnerving it must be to have him entering the house and hanging around at will, even when you aren't there. Especially after a year! It would drive me up a wall. My W left in August and still comes back to walk the dog twice a week. But we have an agreed upon schedule and 99% of the time I make sure that I am not around. At one point, she took some motorcycle gloves from the house, and when I noticed I asked her not to take anything else without asking. I am fortunate that she has been respectful of the space and of my need for detachment.
That said, is it really a boundary if you can't enforce it? I don't know the laws over there, but it sounds like so long as you are still married he has a right to enter the house. From what you say it doesn't seem like you can do anything to him if he keeps doing it (other than getting mad or making angry comments, which doesn't really help.)
