Search Results: he has a girlfriend haha

I hate asking questions like this, first time posting here, please be nice :).
Me and my ex met someone on a game but we broke up and the guy we met online was closer to me than him and we carried on talking (he doesn't like my ex for what he's done) and he's been really supportive and sweet. We're so similar too (music, interests, opinions, hobbies, habits etc.)

Is he flirting? (Sorry long list - I appreciate it)
- He always calls me cute/adorable/sweet/cheeky
- Says "Aww so (compliment above)" when I say/do certain things.
- He *hates* ending the call with me, makes up excuses. Says "I have to, but I don't want to! you're too addictive." (talked for 13 hours but he wants to beat that record)
- He called me attractive once and was like "woah! and you think I'm good looking?" when he saw my pics first time.
- Loves teasing me because I get shy when he does then he says "that's even cuter" and laughs.
-Purposely wants a reaction, he likes to make me jump after he unmutes the mic then says "aw" or will say something to panic me for a split second but we both laugh at it after.
- If I get angry at a game he'll say "aww cute aggression!" then when I say "Stop haha" he'll say "Well stop being cute then, actually don't stop, I like it"
- He types actions like "hugs, pats head, bops nose" he's even sent an <3.
- He makes things for me like pictures, gives me stuff online and likes to give me advice and listen.
- He also had a nightmare about me dying, he said he teared up and he messaged me straight away.
- His family tease him and ask questions about me. His brother has a girlfriend she met on a game and he's planning on moving country for her.

But I feel as if he's out of my league, personality and looks wise and he lives in another country his first language isn't English but speaks perfect English. Plus he has a couple other girls on his contact list (friends? family? crushes?)
