How to recognize if your male bsf likes you? question

So I'm kinda worried that my best friend likes me. Sometimes he talks about him not having a girlfriend, which I find pretty weird. Back then he complimented me that I look like Gwen Stacy from ITSV and that I act like her. And he used to chat with her in c.ai. He also texted me "princess" or something and then he deleted his massage. + his friends started to ship me with him (which is pretty normal ig).

I'm just worried because I only see him as a friend and he's not my type. I find the idea of dating him pretty disgusting and gross. I'd rather date my female friend than him. How do I know if he likes me and what am I supposed to tell him if he does? Act like I'm not into guys or something?
