I can say I am dating a Polish girl, but that is not to say she is any different than any other girl as it seems to run in most of them I have had relationships with
As you said, you are dating a "girl" or have dated "girls". Have you ever dated a woman who truly knows what she wants? I'll admit, back in the days of my youth, I was very fickle....hot one minute, cold the next.....it was about control and game playing.....as one matures, they realize the games get boring and want to actually have a mature relationship of sharing and not just one giving and the other taking.....
What I can't understand is the more I "profess" my love, the more she takes it for granted and seems to say it less her self. When I try to be less forthcoming, she takes it as a reason to be insucure or upset.
As I see it, this is playing games......when people are mature adults, they can express their love for one another without playing games (which is what you are doing....telling her how you feel, then witholding your feelings as a form of control and/or fear). Also, we can tell someone every hour we love them, but as the old cliche goes, "Actions speak far louder than words." Maybe check your own motives and actions and see if they jive with your words. If you are being honest with your feelings for her, and she's not responding the way you would like, then maybe it's time to rethink the relationship.....:)
