Well, he obviously left this girl for somebody else(I'm lucky, I'm here with my someone), and now she's heartbroken (you'll bleed to death on me). I'm guessing she treated him badly since he refers to her as "winter". I'm thinking lying next to her is intimidating... and awkward (heavy breathing). He's saying "You're a ten" sarcastically.
