23. When is it official?

Out of pure curiousity when does dating/seeing somebody become official?

Is it verbally agreed by both parts? or does it just become something more after a certain period of time.

I have never really done the whole dating/courting thing, stupidly I have always gone straight into a relationship to later find we are not compatible. So this time I want to do it properly.

There is just one thing that potentiall puts me off dating. What if while said dating is happening I become very good friends with said person and then become scared to make it official at the possibility of previously mentioned friendship being lost forever.

I suppose there are pros and cons for it. AS there are with just about everything.

(BTW she's quite amazing)
