I agree with doodler. I know that it is "easier" to pretend like you are still a couple, but basically what you are doing is saying that you are OK being in a open M. If you are OK with that, then nothing wrong with what you are doing, however, if you are not OK with an open M, then why are you still thinking / acting like she's your W when she has a boyfriend?
