Okay so I have a question.

Say a girl meets a guy and they have a one night stand. That's all they expected -- just a one night bang and that's it.

Fast forward two and a half years later -- they've never officially hooked up (even though he buys girl Tiffany's/Coach/Louis for her bdays and Xmases), but they still get together (all the time, even when he's had GFs) and it's always like it was the first night. Bear in mind that guy always calls girl and girl HAS NEVER called guy whenever she needed some ass.

Would it be egotistical for the girl to think that she's doing something right? Or should she just assume that guy is just a horny bastard who gets tired of his hand or his GFs that can't quite hit it?
