She's in an early stage of infatuation. Right now, and probably for a good while to come, all she wants is to be with him. She's not respecting her friendship with you, which I don't think is making unreasonable demands on her. That may change down the line, but not any time soon.

What she doesn't realize is that she's making herself into a boring person. The person she's going to end up boring the most is her boyfriend. Some day he's going to want to go hang with his buddies more and spend less time with her clinging on to him. Yes . . . she is the clingy one. Right now, he doesn't mind . . . and even likes it. That will change. Your gf is doing the dumbest thing a girl in love can do. She's never giving this guy a chance to miss her. That gets old to a guy. Eventually, he's going to think, "I can have her whenever I want. Let me go do other stuff. She'll be there waiting when I get back."

So, if you have the patience to wait, she may someday be real glad of a friend to hang out with.
