Short version: I'm stressed about our wedding.

Yesterday I found something weird and I've been freaked out and don't know who to talk to. I found a hidden receipt in his backpack. Early this morning around 6:20 I was grabbing stuff to leave the house and saw an old broken pen by the zipper and a small envelope with an online-order receipt inside. At first I was like... shock for a sec, then my chest hurt out of nowhere.

I'm 26, I work an office job in Hua Hin. Been with him for 2 years and we got engaged just a month ago. Everything seemed normal, but now that we’re planning the wedding the money stuff keeps bringing up doubts and I’m not sure this marriage is the right move.

Here's the thing: I originally wanted to split costs 50/50 because I have no debt and no dependents. I work almost 9–5, but he insisted on covering everything because he wanted to surprise me. I said thanks, but he gets really stressed whenever his mom or relatives talk about the budget — he gets snippy — and sometimes he flat-out refuses my money even when I genuinely offer to help.

Seeing that receipt, it was for personal spending, not wedding stuff. He'd bought collectible items in the last three months and it wasn't cheap. I'm not someone who clings to stuff, but it contradicts what he told family about footing the wedding bill. I was like... what? So confused.

I never thought I'd be snooping through his things, but finding it hurt like a slap. I went quiet. My thoughts kept looping for hours. I don't know if I should confront him — I'm scared this is nothing and I'm overreacting, or that we'll fight and ruin the relationship. I ask myself every day: am I being possessive, do I have the right to know this kind of thing, or am I just imagining things?

He works office hours too but in a different department. He's not flashy; every weekend he likes to sit in a small coffee shop near the Hua Hin market reading from about 1–3pm. But when it comes to important money matters he shuts down and won't talk. I feel like the transparency in our relationship is slipping and I'm getting afraid I won't trust him anymore.

I've got two instincts: one is to have a totally open talk, the other is to keep the doubt to myself because I don't want to cause drama right before the wedding. I know I sometimes panic and overthink, but leaving this alone makes me really uncomfortable. I lost sleep all night over it.

What do you all think? Should I be direct and ask, or are there ways to observe more before I blow up? I'm scared of myself right now. Sorry if this is a messy post — first time starting a thread so forgive any mistakes.

P.S. If anyone's been through something similar, please tell me. I really want honest perspectives. T_T
