Most Helpful Girl
I'm in the same situation. I told him that I'm a bit afraid of the whole dating thing and the bf/ggf labels. We go/hang out all the time anyway, so there should really be no difference. He's starting to get touchy/feely with me anyway. He says I'm the perfect one for him so it doesn't bother him that I'm not ready yet because he'll wait for me.
We're basically 'dating' without all the labels/titles. I guess it's because I'm inexperienced and I'm afraid of being hurt. Until I'm ready to put a title on it, I like the current arrangement. Less pressure.
