I think you have been very reasonable, and your husband is being very unreasonable.
In our house, I always run things passed my husband, but ultimately, I make all the decisions, though sometimes he might come up with something I hadn’t considered.
He’s always happy with the results, but thinks I seem to spend an enormous amount on curtains!
If you both have strong opinions, I guess you are both going to have to learn to compromise, but please don’t let him walk all over you, he will take away the joy of having your own home.
