What are some signs that a guy I met recently might like me over text?

So there's this guy I met through mutual friends and we were flirting and all and we exchanged numbers.
We've been texting daily for a bit over a week and I would like to know what signs there might be to know if he likes me over text.
FYI we've only met once.
