I've been in a situation like this. Normally, I when I think of someone I would want to date, I think of someone taller, stronger, just bigger than me. I think it helps girls feel more protected, which girls really like. Or atleast, I do. However, this past year I meant someone, and we came really close to dating. He didn't fit my normal "type" at all. He was a tiny bit shorter than me, it was only a inch or two. But he is also just a small guy. So I also weighed a lot more than him. I thought a lot about it at first, but once we started talking and hanging out more, I forgot all about it. Plus, it didn't seem to bother him. I liked him too much as a person to not date him for a reason like that. Of course, we didn't end up dating anyway, but it wasn't because of the size difference. But overall i think it can be a little weird at first, but if you really like someone, then soon it just won't matter anymore. I think society just has this idea that guys are always supposed to be bigger than their girlfriends....which that isn't always how it works out, but that's ok.
