The guy I'm just talking to wants my social media passwords. What's up with him?

We are just talking and are friends but more than that. He said he wanted my social media passwords. But we aren't going to date so why would he want that if we aren't going to be dating. Also he was talking about the type he house he wanted in a few years and mentioned stuff that I like and he doesn't. What is up with him?
