Dating a man whose partner died-he has numerous photographs both of her and the pair of them together,,?

I find it disturbing I am sure that he is aware of it but I don't discuss it for fear of hurting him. He evens moves them about, i went the other night and there was a huge picture that had appeared o,n the fireplace as well as a digital frame with flashing pictures of her, her and him and her family. To be honest I feel very unconfortable ther and it is a real pion killer. Should I broach the subject? I now feel that I don't want to visit the house. I wonder if he is trying to tell me something with all these photgraphs? They were together for a bout 5 years and did nt really get on! they have no children although he has 2 adult children. Please help
