That was a really bad turn card! While I don't feel like I am qualified to give advice yet in my poker career, I'll say what I would have done. Not sure if its right or wrong. I'd say there is a good chance the 7 helped the villain based on the way he played it. So I'd say there was a pretty good chance he had trips. I wouldn't automatically assume he had the full house. If the pot were a little bigger I'd say call him down, but I'm thinking that maybe a fold is best here.
