You’re overthinking this. Guys aren’t complicated. Message him and say you’ve missed hearing from him. If he responds favorably, ask if you can call him to catch up. Don’t mention anything about romantic interest. If he doesn’t want you to call him, you know he’s not interested and you can move on without having revealed your feelings. If he does, then you can gauge his interest from the conversation. A lot of guys are afraid to make the first move and these things can die on the vine, which may be what happened here. If things pick back up, just ask him about meeting up again. Sending pics right away always seems thirsty. I would start with messaging and calling and work toward an in-person meeting. Don’t be overly flirty, just keep it confident and friendly to start and see where it leads. If you’re sure he’s interested but doesn’t make the move, make it.

I believe there are tricks to burn the spark right away. There's a good movie where a group of guys found a device that can read the girls minds. So basically if they say what the girls want to hear = they get laid almost instantly. Same thing must be with the guys. It's really hard to know what people think. But if you ask
a lot about them, you can have a clue. Like he may be interested in sports, cars, computers and stuff. If you have some shared interests you can talk about that. I hope it helps.
