After dinner at my girlfriend’s house, I asked you not to keep me, but she said get out of here?

Through your simple description, I think your girlfriend may be joking. Are you asking your girlfriend not to keep you? Your girlfriend. It may be embarrassing to tell you to get out of here, because after all, you are at your girlfriend's house, and your parents don't want to make things go too fast, and then let your parents think about you. It may also be that your performance is not very good today, girlfriend. I was a little angry and told you to get out of here.
