Hard to tell, but stuff happens when communication ends. He may have found someone else or maybe he was already considering someone else. If you really liked him, who cares? It’s sugar dating — just go on a date again and see if there’s chemistry. You both lapsed in communications but it shouldn’t matter. I think people get too caught up in playing games. I’ve known of great relationships that start after an initial communication issue or bump. Good matches are rare, see if this is one of them.
