Sorry, butting in, but I thought that was kind of weird too. Like, they spent the whole movie telling us that he was too short for her, and her boobs weren't big enough for him, and when they tried having sex it was awkward and weird, and then at the end, they were suddenly sexually attracted to each other? Or, sexual attraction didn't matter because they 'loved' each other? I mean, you can definitely love someone, but I think that if the chemistry isn't there... it isn't there. And somehow it either suddenly appeared, orrrr they decided it didn't matter? I was confused about that. He was insecure about his height, she was insecure about her boobs... i would think those two insecurities would maybe come back to haunt them in their relationship. After the other person didn't feel sexually attracted to you for so long, and then suddenly they do, it just seems like something they'd both be unsure about for a while after.
And even dropping those weird proclivities, to just enter into a sexual, life-long relationship based on having a child together and being best friends? That part confused me too.

Although, I probably would've been more annoyed if a romantic comedy had ended without the two leads getting together. I always have to turn off My Best Friend's Wedding and pretend George becomes straight.
