SOUNDS like a yes to me, If i were you I'd pop the question and if you want to make it le ses weird yo can ask over text. I'm sure he will say yes. Good luck :D
Im fairly certain he does as blushing around random people is not a "guy" thing if you know what i mean. I say you go for it and ask him :)
This is a tough question, usually guys are a bit les open to hair feelings between friends SO asking around wouldn't be an option but I know this is a bit weird but you could try just popping the question. I did thats snd it worked so I don't know...good luck though
