Like that. Again and again.
Look at it this way. All things considered, people get together for only two reasons: Because they want to spend time with each other, or because they want to experience the same thing. Take a football game. It doesn't much matter who goes to the game with you. You're going for the game. The event. The thing. If this friend doesn't want to go with you, you invite another one. WHO isn't important. WHAT is.
On the other hand, when the WHO is important, the thing doesn't matter. You want to be in the company of THAT person, whatever the thing is...a game, a movie, a walk in the park. Whatever.
Since you're going out in groups a lot, you need to arrange to invite that special WHO to WHATEVER the group is doing. You don't have to SAY much at all about how special you feel about her. That you keep inviting her and that she keeps showing up (AND vice versa), is all you need to get your message sent and to read her replies. Pretty soon, if she feels the same about you, the THINGS will start narrowing down to what you and she like together; your group and her group will start noticing your absences from the usual events; and the cat will be out of the bag for everyone: Hey! They're going out together! Wow.
Then comes the matter of dealing with everyone around the both of you having their opinions about it. But that's another story.
Good luck.
