Thanks for all the replies.
Irisng, that's some good constructive criticism, however I think there's a lot based on some inaccuracies. For one I didn't say she was ugly, on the contrary I can see how people find her attractive, and many do. It's just I'm not totally consumed by her allure. And maybe that is a good thing. I don't know, that's why I'm here!
That's basically what I'm hoping for, her "looks growing on me". I do realise it sounds incredibly selfish, but I'd rather be honest and get some good advice, than pretend I'm a perfect guy and get nothing. I just feel like I'm cheating her by trying to commit to a relationship when I'm not really sure of my position. As TempusReborn has said, I have yet to get those "take me now" sparks.
I do really want to have those "sparks", but obviously you can't force these things. Sometimes I think, if this is the case maybe I am in love with a friendship, more than in love with a friend. Please forgive me if I seem a tad obtuse, as it's been a long day.
