Search Results: very special first date

I have a crush, and I told him about it, we are pretty good friends, known each other for about 5 months, he is extremely serious when it comes to relationships, like no "hit it and quit it" and when he gets into a relationship he wants it to be special and long lasting, I personally am on the same page so we both have never dated before.
I cannot tell if he likes me or not, while he told me in a 8 hour talk, he told me he can't see anything above friendship, mainly because he dosen't know me that well, he is one of those guys that takes them like years to develop a crush because they want to get to know someone, and even more time to make a move.
We have ton in common, he even told me he was surprised since no girl has ever liked him before, he currently says he likes someone else (I asked, he didn't volunteer) but when he said yes, he was what it seemed like iffy about his own feelings, and he saw my expression change, he instantly started to change it, saying while he can see him dating her, but he sees it as a bro/sis relationship, mainly because of her, she was the first girl that he opened up to and has know for a few years that is why he feels a closeness to her, is what he told me.
He is a major introvert, is very honest and since I have only known him for like 5 months, I don't know if I should just keep hope alive and get to know him on a more intimate level (like the talk) rather then our on the surface friendship and see where it goes, since he already knows I like him.
He has told me he would hate to loose me as a friend and it took him a while to talk to me just to make sure he didn't loose me as a friend... he said he has seen to many friends get into relationships, just to break up and never speak again (we're in collage) The thing is he still stares, we still talk and flirt, he gets jealous of other guys when I give them more attention then him... does he like me and is he just scared try us out? Give it time? Or friendzoned?

**Quick clarification, when I say Asian, I mean East Asia: China, Japan, Korea, Vietnam, etc.***

There is this Vietnamese American guy who I have really taken a liking to. He recently took me out on one of the best dates I have been on so far. He spent six hours with me and joked around a lot, etc. The thing is, I'm beginning to worry that it wasn't really a date in his eyes and he simply considers me someone he could be a good friends with. Aside from the fact that he never texted me afterwards, I've also noticed that he addresses me as my name plus "san". He doesn't do it always, but whenever he likes what I have said, he'll be like "You are so awesome Ashley-san!" At first I thought it was something special and meant he liked me because he doesn't call any of his other chic friends by that title, but after looking it up and realizing it is a honorific or formal title used for people you don't know very well, I'm beginning to think otherwise. Please help! When you call a girl with the "san" title at the end, does this normally mean you respect and see her as just a friend?
