How long should I wait for him to ask me to be his girlfriend?

I don't know how it works in other countries, but where I live, usually during heterosexual relationships the guy asks the girl to be his girlfriend. If it's not clear (none of them asks the other person), then they're not in a relationship (I know every relationship is different, but I'm talking in general)

I have been dating this guy for 8 weeks now. We met online, we texted for a week, he asked me out on a date, and since then we have been seeing each other at least twice a week (now during the weekend, because of our school schedules), and texting all day long (unless we are busy). We pretty much act like a couple: we kiss all the time we can, we hold hands in public, he hugs me, I already met his friends, etc. But he isn't my boyfriend. I know that title wouldn't change anything, but I want to refer as him as my boyfriend, and somehow to feel I'm his only girl (even when I'm pretty sure I'm his only one).

Are 2 months too early to be worried about this? How long should I wait to question if he really wants to take things seriously?
