I still think the guy is just a friend and not someone that she hangs out with and enjoys spending time with. I think I mentioned before that she may be testing the waters w/you to see how you'll react to the news of this new guy. Again, if that guy exists, he's a "just a friend". I don't think it's anything serious or she wouldn't be keeping you on the side to do things w/when he's either busy or just not into doing things w/her.
Whatever the case, continue being yourself and keep those expectations low for now. If you enjoy doing things w/her, continue to do them...but if you think she's using you, then you'll need to decide at some point that it might not be working out for you...but that may be further down the road. For now...just enjoy yourself.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
