Is opening up a good thing?

I chat with my crush when we are playing an online game. He doesn’t say very personal stuff in real life. But in the game he seems to be more relaxed and he talks about how he was mistreated at his previous job and how he was bullied in high school. Which I really love to hear about.
But I dk I read somewhere that if a guy likes a girl he will try to be tough. But I seem to be hearing how vulnerable he is. I wonder if this means that he sees me as a friend only?
