is he flirting???

So I have this guy friend and we're not that good of friends like we don't really know each other but we know enough ya know? And we snapchat pretty much everyday and I really consider him as only a friend, I really do. But anyways the other night he said "well don't worry, you're cute." But he said that because my other friend was jokingly saying I was ugly. (Sorry if this is hard to follow) but Is he flirting???Like if he would of said "you're pretty" I probably wouldn't have thought anything of it cause I would of figured he was just being nice. Haha I don't know. Am I overthinking this?😂😂
