I get this. I think it could be. I've always been afraid of intimacy, and this accounts for other people as well, in real life and on screen. I sort of do a mental/emotional form of seppuku when confronted with these themes. It's to the point that I don't really watch things with love themes, (and often this is enabled by the fact that I don't really care/want to either). There's probably a host of reasons. But when people are intimate I actually perceive myself as under attack, in a way. As if they and the world are suggesting how alien and incompatible I am, or how much a loner I am. I just always sense the implicit message that intimacy is for other people. I'll always just be the hapless voyeur, the out-of-place observer. What's more, is that other people, mostly a mysterious mental audience, let's call them "inner critics", are somehow snidely watching me observe/react. Having said that, I also just find love uncomfortable generally. I think for my own sake, I often think/imagine I could open up to love in my own life, and I think my vision of the future operates on the basis of this belief. But if truth be told, a fear of intimacy, as well as beliefs that I am incompatible/inadequate, are highly likely to cripple me. So I think love/couples in films and in real life are a portent reminder of that.
