My girlfriend and I are having issues. Lately she's been complaining more and more about me. We had a fight several days ago, where she bitched about something I said. I said I'd just keep my mouth shut from now on, and asked a couple times if that's what she wanted. She never answered, so I have been saying as little as possible to her. I just don't know what to do. I don't want to loose her, but on the other hand, she doesn't seem to be happy with me.
