Uncomfortable

All of my suitemates are sitting in the commons area planning their weddings. They are showing pictures of their dresses, what colors they are having, who is in their bridal party, when it's going to be, and how they can't wait to spend the rest of their lives with the man they love. All I can say is that I feel awkward. Here I am 20 years old and I'm about as single as they come. This has been bugging me for about a year or so. I'm not unnattractive, nor do I lack personality. I don't fear commitment, in fact, I would love to feel commited to someone. So, what's the problem? I have no idea. I'm not expecting a fairy tale or my prince charming. I just want to feel loved like I know that I could be. I want to wake up in the morning and they be the first person I think about. I want them to think about me when they wake up. Yeah, I'm goofy and silly and not many people take me serious (that is unless you know my deepest self). But, I take love very literally. The more I think about the more I think that I'm just meant to be alone for the rest of my life. I keep telling myself that I am just married to my dreams. Well there has to be a happy median somewhere. I don't want to be the cat lady. I don't want to be the lady that everyone says "She's not much to look at now, but in her day, she was beautiful" "How old is she?" "32". Yes, I sometimes think up entire conversations in my head. I don't know what's wrong with me. I know it's me because it's highly unlikely that there is a problem with every man in the world. Do I make guys uncomfortable with my upfront personality? Do I come off as a mean person? I don't think I do, but then again I don't really know. I'm not gonna lie, I have taken time to plan my wedding down to the littlest detail, but honestly when am I going to actually put it into action? I don't know, the situation in the livingroom just got me to thinking.
