>>doesn't it usually start like that?!

No. Getting together in a group is hardly intimate, and it greatly diminishes the amount of fun that you can have with her on a one-on-one basis, which is the number one thing I've been trying to get across here. Unless you're planning a Pokemon tournament and you want to show off to this girl by beating the crap out of everyone else, I'd advise against it. That is one of the few times I would ever support getting together in a group.
