I'm obsessed with a girl character in an online game.
So, based on what you were telling me earlier, is this the reason that you are not spending time with your girlfriend anymore?
I love my girlfriend, I just play games for fun.
I understand that you like playing games, but it's not a good idea to play them so much that it negatively affects your relationship. It might be good to spend more time with your girlfriend.
Maybe you should learn a thing or two about love.
Maybe I don't understand the issue here, but it sounds like your girlfriend thinks you're spending too much time gaming, and not enough time with her. If your relationship is starting to suffer, then it would probably be a good idea to pay attention to how your girlfriend is feeling.
