Are cash envelopes helping my budget, or am I mostly hiding purchases from myself?

I put $80 in an envelope marked 'personal' and felt organised. Three days later, I couldn't remember where $27 had gone.

The cash is my own monthly spending allowance after shared bills and savings. I used it for a coffee, a second-hand book and several small things I haven't reconstructed. None was a secret from my partner; we agreed that this allowance doesn't need approval. I just dislike seeing a long row of little card transactions and had hoped cash would feel clearer.

It does make the limit visible. It doesn't show me why I reached it. My partner suggests writing every purchase on the envelope, which sounds sensible but also feels like turning a modest bit of freedom into homework.

Would you track the cash closely, return to card payments, or accept that an allowance can be spent without a perfect account of every dollar? I want the $80 boundary to work without spending more time judging my coffee than drinking it.
