Assuming it was a male friend (hope so, Denver!) then the mysterious friend doesn't really matter... it's the fact that Denver's W was so intrigued that she HAD to meet him there, had to know who was meeting for drinks. Someone with an OM R going on wouldn't care less. I think this is a very good sign.
It doesn't sound like you were a pushover - it sounds like you were a good guy who cares about his SS, who is trying to be supportive of your W and her career. You didn't drop your plans and rush to meet her. You responded perfectly!!! You kept your own plans but also helped her out too. Really, I don't think you could've handle it better.
I understand the impatience but you're doing really, really well, Denver!!!! Slow and steady wins the race.
