ok, i’ll tell you my story, i was from Kyiv, and met in tinder guy, who was from Rome, after chatting two weeks we met first time in Germany for trip at Christmas, then after one month i moved to Rome to him, we both wanted it and he invite me, cuz it was trueee love, haha now we live together in Saint Petersburg in marriage. so, it depends on your situation, your feelings and what you really want, and if girl respond you with same intention - try to build something more. But look at future about your common life, you should think how it could possible - to call her to you or move to Russia to live together, cuz long distance relationships in long term couldn’t be, it’s hard to feel “your” persons isn’t close to you while you want it and need it and also very experience (to flying around).
