Do you have an allocation of money each month for 'fun'? Sorry, this turned out to be really long but I need to tell the whole background story! 
Background - I am a sahm, DH earns about 43k pre tax.
We have a mortgage of about £660pm, savings & investments, an emergency fund. We budget for all monthly expenses carefully, bills, food, insurances, pets, household, phones, Netflix, family eating out etc. all from the joint account. DH transfers enough into the JA to cover all this and puts the rest of his salary in our investments or emergency fund.
Pre covid we each had £100 a month fun money for spending, lunches etc.
It was always a bit awkward, in that I would always feel a bit guilty for having that money and spending it. DH rarely buying 'things' for himself but he would go to gigs and things like that. Sometimes we would do those kinds of things together.
We stopped the fun money during covid as we were buying more joint things, extra food treats etc.
We had a no spend January and decided to start up the fun money again for Feb. We had a few discussions over it and ended up having a conversation where DH was saying he's only going to have £50 as he doesn't really need more than that. He was saying how much do I want, and I just said I wanted my £100. I planned to just buy a few skincare bits, and I've seen a wallet I like which will basically blow the entire £100 and I feel really guilty and like I need to justify buying the wallet even though we budget for the £100 each. I feel like hiding how much I'm spending on it from DH.
I do feel a little awkward about being a sahm and not earning any money myself, and I feel like that puts DH in 'control' of all our money. I have full access to our joint account and I know I could just say to him I want to buy whatever and it would be fine but I don't know, I just feel awkward about it.
My mum was never able to really buy things for herself as we weren't well off when I was growing up and Dad would always take responsibility for financial things. So maybe it stems from that.
Think I just needed to get that off my chest really. Thank you if you've read all that!
