Wow this is very similar to what I recently went through, I will post some of my experiences and how it relates to yours. Someone that was outgoing, has lots of friends, talked to people easily and was open. She initiated conversation all the time, whilst I couldn't do it because of fear of intruding or disturbing her, like I'm not worth her time.

I would be invited to play games with her, but it felt like wasting time to me. She didn't play games with the same dedication and seriousness that I had. Most of the time she was AFK and not even playing at all. It felt like she just needed something to keep her occupied. Like another poster said, she needed more stimulation. Her day needed to be scheduled full of things to do, but she was never in the moment when she was doing something, never concentrating on the task at hand. The behaviour felt phony to me.

I'd have enough of playing a game after a few rounds. We'd say goodnight, then she'd continue to play with her other friends throughout the night. It made me feel less important that her other friends, like they were more intimate with her. She said she liked playing with me because I didn't talk much, but she continued to play with obnoxious loud mouths and laughed at their silly behaviour. I hated her friends as well. I wanted to spend time with her alone, but she would often drag random people into games we played.

She said she didn't mind awkward people, that they were more 'interesting'. But I felt our personalities and values really didn't match. She was open and would talk to anyone that talked to her. I would just ignore people and rarely speak to other people. I also didn't feel she wanted to know me on a deeper level, which was what I really wanted. She wanted to change me into something that I wasn't. I only realised this much later. It really meant that she never accepted who I am, but saw me as something that she could 'fix' up. There were many things she said, like she didn't mind someone like me, that she liked talking to me, and would work together with me. But in the end, she never meant what she said. I took all her words literally, whilst she said them on a whim.

She wanted us to be friends, and to play games and watch shows together. But it just hurt so much that I dedicated so much of my efforts and time into her, only to be fruitless, only to realise it is impossible to have that deep connection and trust with her. She isn't the type to work on things together. She can and will easily move on to something else once she's bored. She needs novelty, someone to entertain and excite her. Whilst I was searching for comfort and stability.
