My current plate of 3 months has just made friends with another girl who I went with once, more or less the same time I was starting to date my plate. With the other girl it didnt go anywhere as we only had one date, but now my plate is telling me about her new friend (the other girl) all the time. Im starting to question weather they talked about me and now my plate is just waiting for me to tell her I went out with this girl. What should I do now, just say non chalantly I went out once with this other girl, or if I meet her (which could happen in the near future) just act surprised then and say something like "oh yea, we´ve met before" ?
