Can I get y'alls opinions? My friend's boyfriend called me hot?

Anonymous
So my friend is a dime. She is extremely skinny and wears lots of makeup and pretty.
She has a boyfriend but they're trying to be secretive about it.
Anyways her boyfriend always looked at me and sends me vibes...
So then one day I didn't know they weren't "public" right?
K so he comes up and starts talking to me and then says we're best friends afterwards. He seemed like he was flirting. Ok so then i was like sooo your ________'s boyfriend huh and he said boyfriend? Why do you call it that? We don't like to call it that and I was like ok...
And today, Halloween i was dressed as a cat and had a skirt and crop top (wasnt slutty only showed an inch of my tummy when I reached up or something. ) and I got hit on by a couple of guys earlier.
ANYWAY THE POINT IS he was like you look hot and I said huh? Thinking I didn't hear correctly and then he said your cat costume is hot (I think, it was barely audible) and I got closer and said what once more and he said your costume is hot and I said oh...
Thanks (awkwardly.)
Should he be calling me hot and flirting when he is supposed to have a "thing" with my friend?
Do you think she set this up?

Also i forgot a huge part.
He ran and told her that I asked him if theh were together.
Sometimes I feel like they're making fun of me. ... idk?

Its so weird because i think the guy I like actually is way more attracted to HER while the guy she likes seems to be attracted to me lol

Every time I see him he just stares at me. He doesn't say hi or anything he just checks me out as I walk by.
