<human>: About 3 years ago I was with a buddy in Vegas and we met a couple really cute girls from Russia. One of the girls and I hit it off and spent quite a bit time together that summer. Her visa expired at the end of the summer so I was kind of in a rush to figure out if our relationship was going anywhere and the language barrier was making it difficult. I told her I liked her, she said she liked me too but she was afraid it would be too difficult to leave if we got more involved. The last night I saw her I dropped her off at her apt. A combination of being sad, bitter, and overwhelmed that she was leaving, kept me from recognizing the fact that SHE LEANED IN FOR A KISS. Or maybe I knew it would hurt more watching her leave after we had kissed. Or maybe I'm just making it up now that I've had 3 years to dwell on it. Either way, she went back to Russia. We still keep in contact through facebook and she says the chances are good that she will come back to the states within a year.

I've been dating another girl for about a year. I'm not in love, but there's nothing wrong with the relationship. We enjoy our time together, we don't fight all that often, she's on a text message basis with my family, and she doesn't mind that I play video games and watch football (unless she's cranky). However, if Russia comes back into my life I have no intention of staying with my gf at this point, and the fact that she has hinted about coming back to the states has created tension in the relationship. I expected to never see her again and just assumed she was always going to be the one who got away. Do I try to forget about her and just be satisfied with what I have? Or sacrifice what I have and take a shot with my Great Russian Buffalo?

Could you distill the essence of the text into 1-3 sentences?
<bot>: The one that got away 3 years ago is coming back. How do I handle this news with regards to my current relationship?
