So I have an issue with balancing two groups of friends. Not even groups just this one particular friend and the rest of my life. I have a friend who I love, she is extremely caring and a really nice person but sometimes she's a bit overwhelming for me. She is extremely hyper. Talks all the time. She has t fill up every single second of silence with some words that might not even make sense, but she has to talk. So she is obviously very very social and is almost best friends with most people she meets even for the first time. I have this other group of friends who I hang out with every now and then and I feel like spending that time with these friends without her being there. Because this other group of friends and me have things in common like language which she doesn't know and other things that come with that. But sometime I feel smothered with her wanting to spend a lot of time together. And I feel like I HAVE to invite her with that other group of friends. I can hear it in her voice that she is very interested. But then when she comes out with us, she's this overly friendly girl and I don't know why I feel really odd about that. She keeps telling them "Oh we should definitely go out again and do this and do that". And not that I don't want her to come out with us, but I want to be able to hang out with these friends sometimes without her there. I don't know if I'm being unfair or the way I'm feeling is legitimate. But I really need to know how to handle this.
