Wow… I’m sorry then…. Yeah then there definitely is something up. Still don’t confront him just yet, try to gather more evidence and then confront him. More evidence that he was doing something wrong when you file for a divorce (if needed, try marriage therapy or what not first) will favor you the courts will look at that stuff, if he catches on that your investigating him then he will likely destroy evidence and etc.

Overall hire a lawyer in secret if you can and save everything you find
