My SiL has always been demanding. I met her when I was 17, her brother was 18 and she was 13. They have a younger sister who is lovely. SiL was a pain as a teen, thought she was special and different.
Going back many, many years when she and her husband and 12 month old child needed a place to stay we let them stay with us. We had only been there a year and there were two bedrooms downstairs and one good bedroom upstairs with two pretty horrible rooms off the upstairs landing. We offered them the nice, big bedroom downstairs but they wanted the bigger, not so nice one upstairs. OK. They put the baby cot in the horrible room, it was a place I would put luggage not a baby but they didn't care.
I had cats (PFBC) and asked them either not to bring their cats or for to let ours get to know them before they took them to my home. Did they Fuck, they snuck them in and fed them in the horrible room that the cot was in. When I found out, there was tins of moudly Whiskas and a crusty spoon. I let the cat thing go because it was family.
We had a dining room that we adapted into a lounge for them but I had to go through it to get to the kitchen. My DH worked away a lot and I worked full time and I would come home to her cooking dinner for her DH and not even a plate for me. She would take her friends, who I knew, into their lounge and give them a meal and not offer me anything. Most of the time that wouldn't bother me but it was the show she put on for her friends.
She smoked, and I did at the time but she would let her toddler put juice in the ashtrays, I came home one day and my bath was covered in an empty ashtray, did she clean it up? NO.
I think the worst was when she thought she was pregnant. She left all her pee tests all over my bathroom sink. DH and I were trying, she didn't know that, but who the fuck leaves their pregnancy sticks on the sink?
When my DH, her brother came home from Offshore she had a meal on the table for him and cleaned the house, fucking bitch!
My DH knows how I feel and her younger sister knows and they agree that she is selfish but I cant seem to let it go. DH comes from a family of non-communicators. I have told him that I would be ok never seeing SiL again but I want to tell her what a shit she was to me.
In case anyone wondered, I kept my house clean, I did more than I would normally have done and I did look after my nephew. I didn't go upstairs because that was their area and it was only when I saw my nephew in the shitty, horrible room that I saw all the tins of food and crusty spoons, they were disgusting. I threw out the old cans and cleaned the cats food bowls.
WIBU to tell her or should I just let it go, she is still a selfish woman to this day.
