Don't be scared, if she's the right one, there is no reason to fear the big "C"! It really isn't so bad, it may be tough for some people, but for those that don't have a problem with it, it's great. Don't ask my husband for advice though, he can't even spell committment it scares him so much!
There's a great deal to be said for taking things slowly. Why do people always assume that a laid-back attitude in relationships equates to commitment-phobia? Whatever will be, will be and I don't see how pushing the issue by rushing things along can be beneficial for either person involved.
