Hello, I am a long-time lurker and have decided to ask a question.

My partner and I have been together for 6 years and have lived together for 1 year. We are not married, it's not something I am personally interested in (I know that this doesn't necessarily fit the red pill ideal.)

I've always known that he and his mother were close and have tried to be understanding. However she loves home buying and decorating (she used to be an estate agent) and in his last house ( I was there half the week, every week), she practically picked all the furniture and decor which he has brought with him to our home. So we both moved in together, he owns the house whereas I do laundry etc. and pay what I can (I work full-time but was a part time student until recently so didn't have much money and have some debt from helping my family). His mum comes over once a week to clean the house (something I disagreed with and the plan was that I would do all the cleaning so he wouldn't have to pay his mother once a week. He had agreed but changed his mind after we moved in, as she cried about it).

Anyway, we are in the process of decorating the house and my fears have come to light (fears I had discussed with him previously). She is deciding the wall colour, type of paint, room layout (merging the dining room with kitchen) and even how to do stuff like bush trimming etc. I can't stand it and today I feel like I mean nothing, like my opinion is just worthless to him. He asked me to masking-tape the skirting (ready for painting) and he told me how to do it and I said 'sure I'll help but I'd rather do it this way'. He wasn't happy so I said 'I'd prefer to do it this way' He burst out "She knows how to do it, she has experience!! Listen to what my mum said" Obviously she had told him to do the skirting this weekend and how to do it etc. And he took it seriously.

I don't know if I'm being crazy for disliking his mum being so involved in our home. I understand that I don't own the house or pay much, so I've mostly been accepting of his ideas. But his mum has so much power over the home, when she cleans the house we're both at work and I feel like she's deciding what she wants us to do etc. I love my space and privacy, my family are very different and non-intrusive.

I'm not sure how to explain this to him, I have tried to before but he doesn't see it.

Sorry for the long wall of text.
