So....... WTF? 10 points to a reasonble insight of my problem?

I think you should ask her about it. Communication is key, don't just ume something and act on that, even with people's advice. You need to know where she stands on the issue. Just don't make it seem like you are pushing to have again, that might just lead to a fight. Just something like, "Hey, I know we haven't had in awhile and that's fine! I was just wondering how you felt about it and if you think there is a certain reason why, just because it seems like we are growing into a new phase? just wondering where you see us going and how you see our relationship growing?"
