hey people you know I met a polish girl on internet and of course she's pretty , tall, blue eyed etc and well,and it was easy to talk with her ..mm to have a good conversation etc and i fall in love with her and she seemed okay with it we used to talked like every day in skype her mom knew about me and etc she seemed interested in me and we were together for about 2 months as a couple but then i dont know what happened but to her it was just a game and she didn't mean that with me but she told me many times that she loved me and she wanted to meet each other and those things you know and now okay we are still friends but i have been seeing that she's doing something like what she used to with me but with another guy so tell me guys, is this common?s i feel like a stupid now...
