How is Romantic Love Expressed in your Country?

Sometimes I feel guilty about the amount of time I spend thinking about things that, when I sit back and look at the bigger picture, probably shouldn't be so important. But lately my brain has been obsessing over my relationship with my boyfriend. And more broadly, how love is (should be?) expressed in a romantic relationship. I still feel like I need to apologize for the superficiality of this post, but I thought I would turn my confused heart and mind over to my fellow PulseWire sisters and ask you:
How is romantic love expressed in your country? I know every relationship is different and every person expresses things in a different way, but so often it appears to me that after a man has wooed a woman, after he has "gotten her" so to speak, he decides that he doesn't have to make an effort anymore. Even if he "loves" her, he doesn't need to do anything special to express is. This, at least, has been my experience. Has it been yours? Do men in your country pursue women, looking for victory, and then when the challenge is over they appear to get bored or become apathetic about the relationship?
My boyfriend tells me he loves me pretty much every day. I believe he does, but I don't see any real expressions or actions of it. He did at the beginning of our relationship. This is how I can recognize that they aren't there anymore. And I guess I've just become so curious if women everywhere experience this, or is it just in North America where the men become complacent with their expressions of love! Again, I know I'm speaking in generalities, and for that I apologize, but I'd really love to hear any comments about this question. Thanks for reading!
