<human>: Okay so some background first:
I absolutely love this girl and I will make her my wife one day (we're only 24 right now, so a couple years). 110 percent sure she feels the same. She's my best friend and I couldn't see myself with anyone else. We both have our respective groups of friends but rarely go out "alone" (happy hour after work with colleagues is not really "alone"). We've lived together for 1 yr in college and so far 1 year out of college. 

Problem:
This past year living together has been kind of different (at least for me). She seems to have gotten very "clingy/needy/controlling". She has absolute no problems with me going out with friends or us going out in general which is strange. The issue she is having seems to be "me" time. She gets really mad/upset/angry when I stay up while she goes to bed, which is early sometimes (this maybe happens twice a week at most). The only "me" time I have is when she is doing something herself. I am now freaking out emotionally inside because I can never just read, play a video game, surf the internet or just watch TV.

I love spending time with her and always have. I've tried speaking to her about this but she just gets very defensive. I feel like I'm doing everything else right in the relationship. This is practically our only issue at hand. Any advice on how I can work through this with her? Any similar experiences? What helps ladies!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: = gf is having a problem with the small amount of "me" time I want. How do I make her understand and be okay?
