As I'm typing this, my flatmate sits on the sofa opposite. He's on his phone, oblivious... just like he's always been ever since we've met. I don't think I could date him. He's obnoxious, our views clash on different subjects, and we have only a few common interests. But if the chance to ever sleep with him cropped up, or he suggested a friend's with benefits relationship, I would be totally down with that. I know he's a flatmate, and that anything further paired with this would be a bad idea. I just needed to get this off my chest. Cheers for listening.
Is there any flirtation between you two at all? If so then I'd suggest the friends with benefits thing. Plus... he's a guy. I'm pretty sure he'll do anything for a friends with benefits relationship with his own flatmate...
