Then she went to her room. A little while later I knocked on her door and opened it. Right after I knocked she said, "What??" - in a really nasty tone. Then she said, "Don't just come walking in until I tell you to come in. I could have been changing or something." I said she walks into my room whenever she wants to.
I told her some conversations are important and some aren't. I remember the ones that were important. That's how memory works. Then she said, "Don't give me a lesson on memory." At that point I just turned around and walked away, closing her door behind me. I guess I finally got it - not to get into this cr@p with her. As I was walking away she was still talking.
I need to know why you went to her room after the conversation the two of you had. I am assuming as soon as you entered the room you wished that you had not and that is why you left.
She not only pushed your buttons on this occasion she got into your head and made you question yourself. That self doubt I am assuming is what made you go to her room and try to defend yourself to her.
You know the drill Ken. Stop letting her pull your strings. Stay steady and have a great weekend.
