NO! I don't need his permission for what I want. I'm an adult and fully capable to decide for myself. I've worked all my life since age 6-7 in potato fields that young, and as an adult and have earned my own way single or married.
If I want something I just go out and buy it. I have a nice retirement income that arrives every month and so does he.
I do not hide anything from him. It is all out in the open and if he dared say anything.....well let's just say he knows better.
I don't mess with his toys nor question what he buys or not and he knows not to mess with mine.
