Its not unreasoinable to be feeling as you do. You're disappointed. That's valid. I don't see why waiting a bit should be a problem until you get through that. That is valid to ask for I think. Its also valid that she go ahead with this couple and see how it goes. For you it means a big deep breath in, telling yourself its all good, this wasn't meant to be and now its back to the drawing board. Once you're disappointment settles then get back to dating amnd enjoying the time ytou have while she is "entertained." I would give yourself and her a time limit that can be moved though. A couple of weeks maybe? Then see how you feel.
