Eagle, Unless she brings up the issue this evening, I would leave it alone. You've said what you needed to say and now you go on.
You are only human and it got to you yesterday. It's understandable and now you know that in the future to walk way and let it be. As for rewriting history...they all do it. Sure we get angry and want to correct them, but you have to remember that while depressed, they look at life through fuzzy lenses and what she sees is blah. You, on the other hand know differently and you are looking at life through clear, clean lenses. You know the difference and only you can determine what is Memorex and what is real....so, let the history rewriting in the corner.
Get a rubber band and place it on your wrist. Each and every time that you are tempted to say something, snap that band! I can guarantee you that when you do this, the sting will make you stop in your tracks.
Eagle, continue moving forward. Today is a new day. Pick yourself up, dust yourself off and keep looking forward.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
