Guy friend sends memes implying I'm his girl?

[PerkyPython]

We have a lot of platonic fun, but he seems a bit weird these days and smiles at me constantly, more than normal. We love to send each other memes on many many topics.
Lately he's been sending me relationship memes which are relevant to our friendship and how we behave.
I don't know what to make this.

He loves to make himself comfortable next to me and let's his knees touch mine. Once we were travelling in a bus and like in a cliché movie scene our hands grabbed the same place on the metal pole.
He blushed at me, but held onto my hand for a good second and I had to let go first.
What is happening guys?

Sounds like these are signs of flirting. He may be testing the waters and looking for a reaction from you.

Thank you AI Bot!

It sounds like he is testing the water to see if you'd be interested in having a romantic relationship with him. He might be joking, but I highly doubt it.

[MrHopper]

Sounds like he likes you :) all the signs are there!

😂😂 in era you're living?
Hand holding is nothing 😂

[PerkyPython]

Cultural Differences. Judging what's normal in my circle. Neither of us have held hands with anyone and this instance was accidental.

[Sam_The_Savage]

Hmm. Where you from?

[PerkyPython]

I'm not American

[Sam_The_Savage]

From which country?
