I have found physical evidence of my H's A, and yes it gets you boiling mad. But from my experience, that is just the initial rxn. I have run off and let this steer my interaction with my H, and you know what? I felt worse afterwards. It didn't make it better. So, reacting will not make you feel better. If you want to tell her off, write her a letter and post it here. Don't tell her off. It will only bring out her nasty defensiveness and it will make you feel worse that she doesn't crumble from feeling bad about it. It may be best to avoid much interaction with her during this part of the coaster. I just keep telling myself...I can always tell him off. If I put it off today, I am not wasting my chance to tell him off. But once I do, I cannot take it back. So by waiting, you aren't losing anything. This isn't fair to you, you feel betrayed and like you don't even matter. You are betrayed, but you do matter! Your W is just being too selfish to consider anyone but herself right now. Look- she even wants to be selfish with the time she is at the hospital with her father. So she isn't just being selfish with you- maybe that can help you not take it quite so personally.
