Not that confusing IMO. He suspects you are dating or exploring the idea of it and he doesn't like it. So he is around more, asks you pointed questions about where you were and what you are doing, watches the front of your place with his camera that he keeps turning on. Seems obvious to me anyway. Keep doing what you are doing FS. I think you are in a good place.
Yes, I think this is spot-on. That doesn't mean he's not having a grand old time sleeping around himself FS, but of course he is going to hold you to a different standard.
