Do you think he’s into me , or polite?

I went out with this guy. I felt it went well.
He told the server it was one bill.. didn’t give her the chance to ask.
Just before leaving he gave me a hug and said he’ll text me next week to make plans.
I messaged when I got him and thanked him, complimented him too.
He’s not a big texter to start.. so it was short and sweet.. no compliments or flirting.. sent a smiley saying thanks after I complimented him and told me to sleep tight.

Haven’t spoke since that , but every time I post a story on social media he’s one of the first people to view it today writhing a minute or 2 after I post … no it’s not casually just flipping through stories , yet we haven’t spoke.

Not sure how to take it especially since he isn’t a big texter anyways.

Any input?
