<human>: So there is this girl that I have been talking with for the last 2 weeks, I've known her for a year. We've slept with each other numerous times, we really enjoy each others company, people in my group has already started calling her my girlfriend. We are part of the same friend group. A mutual friend dated her for a while but split 6 months ago, and I asked his permission before I initiated anything with her. Anyways, her last two relationships were basically marriage (which ended in divorce), then our mutual friend. They were together for 8 months but never made anything official. 

I'm not really into that... I don't like things being vague. I really like this girl - she's told me that she hasn't felt the way she feels about me since her marriage. She's very, very much into me... we do all of the things couples do, go see movies, talk in bed for 3 hours, etc. It's obvious that we are very much into each other!

I just don't know how, when, or if I should initiate the "lets make things official" conversation. We've kind of hinted at it, but nothing explicit. I don't know if she is waiting for me to, or if she doesn't want me to. I don't want to ruin things just because I want things to actually be official. I don't even know why I'm so hung up on the "official" part of it all. 

Advice?

Can you condense the text into a few key points?
<bot>: I like a girl, her last relationship was never official, should I try to make it official and how do I do so?
