I am so sorry. I don't know your history, but I'm getting the picture. You can choose to either actively begin poking around and looking at bank statements, etc., or you can just sit back and watch his behavior. I would also agree that it's unlikely that you'd forget a picture like that or the specific conversation he says you had about it. That response is the most concerning to me of all. If it were me, I'd look for other things now, but you clearly have other history, here, so I'll simply say that I'm so sorry, and I do hope it amounts to nothing.
