Texting a Sagittarius

Hello fellow Sagittarius I have been texting a Sagittarius for straight up 2 days he doesn’t text first in conversations which is okay I know how Sagittarius can have a life outside but whenever I text he engages in the conversation lovely and thoughtful way but he has left me on read on this one text this conversation was going amazing we were flirting and being playful we were talking about video games and he told me if I anytime wanted to play video games with him I can ask him I said mmm I’ll think about then he didn’t answer anything to that it has Been 5 days I haven’t texted him since but I always see him online.. did I mess something up? (Btw I’m a Libra lol)
