Um, Mate, it is a little awkward for me to have to say this out loud and on the Internet, in front of everyone, but I don't think that guy is your new boyfriend. I'm sorry.
As you seem to be having trouble seeing clearly, I am going to hold a mirror up to you
And then remember this other thing you said 4 hours ago "instead of smiling at me and looking all eager and excited like the first fake boyfriend, this one always looks kind of irritated"?!
Ipso facto, that guy you keep seeing around is just some guy you keep seeing around. I think it may be important to learn the difference.
It's like Aussie Male. He wasn't anyone's boyfriend. You see, readers, before K's boyfriend came along we used to see this other guy around. All the time. For a long time he didn't have a name and then, weirdly, K and I were seeing a play and this guy, who we'd been seeing everywhere for months was sitting RIGHT NEXT TO US! At intermission he left his coat on his chair and out of curiosity we looked at the label. The brand was Aussie Male. And after that, so was he. Anyway, the point is, he wasn't a boyfriend he was just that ubiquitous guy, Aussie Male.
In LB's family there is a story about one of his brothers who once asked their mum "How do you know when you are going out with someone?" People like to laugh at the adorable naivete of this, but you know he has a girlfriend now and I think there is no confusion about the girlfriend/boyfriend thing. Sure, the blurry line may be different in fake relationships, but, if you like, I can give you LB's mum's number.
