While she was at work I played the game the entire time.
Could you expand on that?
Yes, I played a soccer video game all day when my girlfriend was working
It must get lonely when she is at work. I am glad you found something to at least occupy your time.
It's okay. I'm kind of glad she is not here. She hates when I play video games. I will just hide the evidence
It's okay that you play video games, but it's wrong to lie to your girlfriend and purposely hide things from her. Perhaps you could have a conversation with her and explain that playing video games is a hobby you enjoy and ask her to be more open and understanding.
