Is he catching feelings?

My friends with benefits and I used to text purely to arrange a hookup.
I mean just the other week we had the “This is just sex” chat, however, we’ve now gone from texting to arrange a hookup, to texting all day everyday, and talking about normal day to day things seeing how each other’s days have been etc.
Anyway, he just texted to say “Seeing you this weekend is the only thing that is getting me through this week”
Does this mean anything?
Am I overthinking and reading into this way too much?
Help!
Is he catching feelings?
