Long story short this girl and I have been friends for about three years now. When we met we were both seeing other people. The relationships with those other people both ended and we were each there for the other during our respective breakups and became pretty close friends. We're both military and stationed in Japan. We haven't seen each other in a little over a year, but I'm taking leave in a couple weeks to go visit her. I want to see if she and I can't get a little something started while I'm there so my question is this: is the friend zone penetrable? And if so what sort of game would work best on someone who already knows me?
