<human>: I am currently in the second of two quarters abroad. Last quarter, I met a girl from my university (let's call her Emily) and initiated a relationship which lasted the three months that we were together in England. By the end of the quarter things were very involved, but we had no pretense about maintaining a long-distance relationship, as she was set to return to our university in the states while I was moving on to Spain for another quarter. To quote her, "You are going to be in Barcelona and you should have a good time and shouldn't worry about anything back home." All that was agreed upon beyond that is that we'd meet up for dinner sometime when I was back. Fast forward a month and I'm in Barcelona meeting new people. One of which is a really amazing girl who I am very interested in (let's call her Rebecca). But I'm still receiving constant emails from Emily saying how much she misses me and how we're going to do all of these things together when I'm back, and I am guilty of reciprocating (I do miss her, obviously, and still care about her very much). After holding back on pursuing Rebecca because I felt a bit uneasy about the situation, we've begun hanging out together more and have made out a few times. I don't think I'm really transgressing when I think about it, but at the same time I feel like I am being somehow deceitful in that Emily seems to still have the notion that we will be together when I am back (and I'm not totally opposed to the idea). But right now I just want to see how things develop with Rebecca without any expectations or reservations, and at the same time I know I am heading for a nasty situation when I come home to the states and have to tell either one or the other person that I am not interested. I think it will definitely look like I am playing one of them, though that's not what I feel I am doing.

Summarize the given text in a few sentences.
<bot>: Pursuing a relationship with one girl from my university while abroad, while at the same time potentially misleading another girl back home into thinking we will still be together in the future.
