Here is a little background to my story:
My partner and I have been together 4 years and I've always known that him and his mum are close and that he does everything she tells him. Her and I have always gotten along, but since we moved into a house in the same suburb as her, and have since fallen pregnant, things seem to have taken a turn. OH's work is mostly around our area, so everyday he goes to his mums and she will have lunch waiting for him. If i'm not home to make dinner then she will make his dinner for him and had made comments to him saying that she thought I would have prepared something for him to heat up. She has always been a homemaker and never had a job outside of the home. Her children are all in their 20s/30s but she still doesn't work because she would rather be there in case the kids need her. When we first moved we had issues where she would come to our house while i was working and clean things. Not just a vacuum/ dust but go through washing and put it away in our drawers, strip the bed and remake it, rearrange the bathroom cupboards. I was infuriated and found it really invasive of my privacy. OH would stick up for her saying that she's only trying to help and that she has always cleaned his things and to stop overreacting . We had massive fights over it. No one wants their MIL in their underwear drawer!! Eventually he obviously told her how angry it made me and it stopped, so things improved for a bit with no issues.
Now we are due in October and have started to prepare the nursery. I told OH that the wooden sliding door to the nursery was really noisy so we would be best to grease the door runner/ replace the door/ whatever it is you do. Well he has gone and mentioned this to his mum and her reply to him was that "The baby has to learn to sleep through noises, you have to have a bit of noise around or else it will have sleep troubles later on"... seroiusly? So the next time i brought it up about the noisy door he told me he's not going to bother because his mum said it's fine.
Now her is my dilemma:
OH invited her to come baby shopping with us over the weekend because she wants to pay for half of the nursery furniture. I am very grateful for the offer but I also feel like she will try and take over and pressure me into things Im not interested in. I saw a Baby Bunting catalogue at her house with certain things circled and I know she has already picked certain items out He will agree with his mum on everything and it will be really crap. I'm so not a confrontational person and my style is to agree and hold things in until i burst at a random moment lol. I feel that she has good intentions but she always need to feel involved and have an opinion!
Would it be rude to ask her not to come shopping?
