I really do understand the disappointment, but I saw this coming when you posted earlier that you thought you two were going. You know this too. Shake it off and keep moving forward.
The real issue is whether this is a boundary issue for you. Like Coach said, if it is something that bothers you, then bring it up to her, but do it so that it does not come off as you being needy. Don't know, but it sounds like it's a girls only thing though.
