I wrote a novel about my experiences thus far with my (probably) Nmom... if anyone wants background. It is in a LONG post entitled "Need valadation..." or something.

My mom is finally able to get around on her own, three weeks after knee replacement surgery, where she refused to get outside help and basically dumped it all on me when she realized that she was not all-powerful and able to take care of herself and her house and pets.
I was supposed to go by on Friday and do some chores for her - laundry, take the trash out, any grocery shopping, etc... She called me up all friendly and chipper at work before I left and told me that she was feeling pretty good and wanted to go out to dinner. She acted like she hadn't just spent the last two weeks calling me awful names and forcing me to be her caretaker (because of her lack of planning). I was not wanting to socialize with her at all, and only get through the time spent caring for her by disconnecting my emotions as best I can and treating her like some stranger so I don't lose my temper every time.
I agreed to take her, only because I realized that she hadn't been out to a resturant in over 3 weeks and the only outings she has had had been to the doctors. I get over to her house, do the chores, and she starts asking me if I was hungry. I told her the truth, that no, I wasn't, I had a big lunch, so she should pick where she wants to go, since I don't have a preference. She informs me that she wants to go shopping "this weekend" and I ask her why she needs me to go with. She gets a hurt look on her face and says, "well, I guess I don't."
She gets angry with me because I'm not all happy and chipper to be going out with her. I take her to her choice of resturant. It is a STUPID place to go if you are barely walking well and can't stand for long periods of time... she picks a #$@#! cafeteria style place that you have to stand in line and slide the tray down the rails and carry your own tray to the table... I asked her if she had considered the amount of standing, and I get "oh, I didn't think about that."
We get food, and I tell her I am not comfortable with her paying for me. She gets angry with me again. I don't want her paying for me because I figured out that any time she give me ANYTHING, she considers that "making things even" between us - she throws money or stuff at me trying to buy me off. We used to alternate paying when we still enjoyed each other's company, but it has been a LONG time since then, and I have no idea whose turn it is, and I just didn't want to feel like she was buying me off for the price of a cafeteria meal. She orders the register girl to give her the check and refuses to let me see it. I decide to drop it because anything else is going to make a scene, and I am just not up to dealing with it right then.
We get to the table and she starts trying to start a fight. She demands to know what my boundaries are, so she will know what she is and is not allowed to do. There is a nasty, condecending tone in her voice, and I know that anything I tell her will get her angry and cause a big fight. I tell her I am not discussing this with her right now. I am tired, I had an awful and very long week, and I am not fighting with her.
She gets weepy and says I am "pushing her away" which is her parroting what I have been telling her for the past year. I tell her again that I am not discussing this with her right now. I continue with the inane small talk, she complies, and we finish an awkward meal and I take her home. She brings up me not wanting to go shopping with her, and that she only asked because "that's what mothers and daughters do!" and that it was obvious that I didn't want to spend anymore time with her.....
Well, DUH woman!!! You treat me like an indentured servant, yell at me, call me names and expect me to ENJOY spending time with you??? What color is the sky in YOUR world???
I cannot believe how out of touch with reality she is... as if her being in a good mood erases everything bad that she did to me!!
I talked to my dad this past weekend, after the latest incident, and he told me that in the beginning of their marriage, my mom was a sweet, kind person and had many friends. About 5 years into it, she had a dramatic personality flop - and became very self-centered and selfish. He felt like she was a completely different person. She left my dad shortly after that, and he has never understood what happened and why she became what she is now, and he agreed that she has always put herself before the needs of anyone else.
I have been doing a lot of thinking about this, and the thing that really angers me is the feeling of being taken advantage of all of my life. I have been made to feel responsible for my mother. I have been made to feel guilty for having a nice day spending time with my husband or getting myself a manicure, if I didn't include my mom.
So, she is currently giving me the silent treatment, since Friday. She told my sister that she just was sooo heartbroken at the way I am treating her.
Yeah, well, I've been heartbroken and angry and sick with worry for the last few years.
I hope the silent treatment continues for a while...
