How to word this right…

Hey ladies!

I’m wondering how to bring up naturally and word a conversation with this guy I’ve been seeing for almost 3 months now besides “what are we?” I don’t want to bluntly ask and I feel like it’s a terrible way of starting off a conversation like that so I was wondering if there was a better way!! Also how to ask how we can be official on fb too, it’s something important to me but I know for some it’s not- I just don’t want to come off as clingy or awkward haha

Thanks!!
