I think I'm about to start a relationship with someone, but before I met her I had planned a valentine's day date with someone else from one of my classes. If this becomes a relationship within the next couple of weeks, what do I do about what I originally had planned? I can't un-ask her out; what if she turned down other people based on what she already had planned with me? Plus, I had been extremely interested in her, and if this other thing doesn't end up working out, I still want to keep it as an opportunity.
Right now I'm thinking that what I'll do is keep what I originally had planned, but as a friendly thing, and suggest going out with the other girl the day after (which is Friday, works better anyway). Is that a good idea? How big of a deal is this situation actually?
