DP went out last night on a works do in the city centre.
Went out at 6pm came back at 3.30am with a pizza, slept on sofa til 7 then came up to bed.
Pretty standard no issue
I've went in his wallet to get money out for a takeaway he wants and found £175 in cash, £10 and £5 notes.
He rarely has cash and work do's are always paid for, drinks food ect all night. There's no need to take money out other than a taxi.
I've thrown a strop and made him show me his banking and he withdrew £200.
He's got no explanation and I don't know wether I'm being unreasonable in being annoyed and overthinking things?
