She Drives Me Crazy

I love my girlfriend deeply and we have been together for a year and a half. I want to scream at times because she cannot keep her appointments or her conferences straight.

Again, last night, she sprang it on me "Oh, I have a conference in Albuquerque next Wednesday so I will be gone Tues night and be back Wednesday night." Why didn't you tell me this? "Well, they sent me the email but I think I deleted it and didn't remember until they sent me a reminder this week."

Then she will do things like "Oh, I told Congi that I would meet her at the gym at 8pm." You're usually in bed by 8:30pm why so late? "Well, that's the only time she can get a babysitter."

She changes plans almost randomly. It makes me crazy. I even went so far as to accuse her of cheating on me last night because she changes her plans so much. That didn't help.

She has two or three ways to keep track of her schedule but she doesn't use them well. She has been diagnosed with ADHD but she is not medicated and we're not going to start that.

What do I do? What do I tell her? She knows it makes me crazy. I am not the type of person that likes to change plans at the drop of a hat. I feel abused every time she changes her plans.
