Always amazes me the amount of people who 'helpfully' say things like
"Just ask him OP"
Clearly they have never been cheated on. Cheaters are liars and manipulators.
The OP and others need to know and have proof for their own peace of mind beyond reasonable doubt so they can steel themselves against the inevitable gaslighting and manipulation.
Remember especially if this is a first time, the OP will be shocked, sickened, sucker punched and worried about their love, family, home, kids, life, finances and feeling shock, pain, worry, anxiety, self-doubt and all mixed up with a massive dose of hope that it's something innocent.
That is a powerful mix for a cheater to manipulate. That is why those of us who have lived through it always suggest getting more evidence, screenshots etc
There's always a few
•oh the trusts gone anyway
• just ask him
•just have an adult conversation
Severely missing the point.
OP you need to know what's going on. I would
Hide his phone, search hidden folders etc, heck everything you can to see if another bank. Account etc. Watch & wait.
