She may meet another guy between now and your next date and decide she'd rather be with him. She may even have already decided that you'd make a better friend than lover. She may do or have done all of those things, or she may be madly head-over-heels in love with you. The direct approach here will likely only result in making everyone uncomfortable and may even destroy what you've built up so far. So my advice to you now is to take things slowly and just go with the flow. If you don't set any expectations of how this is going to develop then you won't be hurt or disappointed when they aren't met and if things don't work out for the best you can smile and truly say 'all the best' to her.

Or that's my two cents, anyway.
