<human>: It's not just with my current girlfriend, but my exes as well. 

I don't want/need a lot of friends. Currently I have one best friend, my girlffriend and people I talk to at school and work. I don't feel the need for more interaction with people as it is. 

I'd love to focus my entire life on myself or my relationship. I want the two of us to live in a bubble. I feel very insecure when my gf does things outside of it. It makes me want to control her. I feel uncomfortable with her using facebook, going to a lot of party's. All I can do is pretend I don't care and wish her fun times. 

I'm never really happy in relationships because I don't feel good enough. I always try to be the perfect boyfriend, but I feel that I will never be. There's always an image of the perfect 'me' inside my head that has way more fun with my gf than I am. It's tiring. I have expactations of how things should go in my head. The real thing is always less nice. In our heads we can make everything perfect.

Sometimes I feel it's better to stay alone. This way there are no expactations, no insecurities from my side. I can't compete with other men. Maybe for a little while, but experiencing the same guy every day of your life is getting boring.

Summarize the given text in a few sentences.
<bot>: I want to break up with her, because I want to be too perfect and I can't which results in feeling insecure, controlling..
