Search Results: he calls his friends sexy

So, this guy (Caleb) and I have been chatting on Snap and Insta for the past couple days on and off. We have classes together, and lately we've somehow opened up more to each other and become very playful/teasing to one another. For instance, Caleb will purposefully hit my leg with his bag and smirk at me and say "oh sorry" in a teasing tone and I'll laugh and roll my eyes at him. It's just little stuff like that.

Additionally, I've complimented him on his writing and how he's a cool person in these messages, and he's called me "really sweet" at least three or four times. He found out that I write too, and said that he's sure my writing is "much lovelier!"

Anyway, my question pertains to this: Caleb found out that a different guy friend of mine called me "sexy af" without my glasses, and this same guy turned around and told me I looked ugly with them on. Caleb was like "omg who said that?" And I told him the guys name, and etc. Caleb replied with, "He's so stupid I promise."

We both have low self confidence and it seems we try to build each other up. Like I called myself a doormat for just being awkward and not assertive enough, and Caleb responded, "You are not a doormat!!"

Those responses... coupled with the behavior... do you think Caleb likes me?
