<human>: Give me the gist of the text in a nutshell

Please, serious replies only. Two year relationship. I'm [30F], he's [31M].

Last night, I was doing bills and really needed some business envelopes and couldn't find any. Since my fiance does a lot of work at home, I figured he had some in his desk. That's when I found a recent bank statement, which he seemed to be hiding because it was located in a drawer that he usually keeps locked. I didn't think much of it until I saw the name of the bank and realized it was different than the one we use. The account had a balance of around $715,000.

When he came home last night, I didn't say anything. In fact, I just went straight to bed. I feel betrayed and disappointed in him. I'm not a gold digger, so I don't understand why he kept it a secret from me. Before we got engaged, we had a serious discussion about finances. We laid everything out on the table so there were no surprises and no secrets. Now this happens.

This morning, I wanted to confront him about it, so I got up early and went downstairs to check his desk for the statement and it was gone. I don't know if he hid it somewhere or threw it away, but now I have no proof. I checked the shredder but nothing was in there. It's like it never happened.

Needless to say, I'm struggling to figure out how I should approach him about this. I don't want him to think I was snooping through his stuff because I wasn't. The more time that goes by, the more mad I get thinking about it. He'll be gone for most of the day, so I can't talk to him about this until tonight.
<bot>: Fiance is hiding money from me and now the statement is gone. I don't know how to approach him about this.
