Son, you should have known you fucked up when she didn't "let you" see your friends. This kind of behavior don't just manifest out of nowhere, she's probably been a controlling cunt all her life. Even pining over her shithead ex she turned it into "I would have taken him back" like she wasn't the reason he dumped her ass in the first place. There's no protecting your assets, the courts will find them. Your best bet is to make her want to cheat on you and then use that as leverage in the divorce proceedings. Best of luck, your woman sounds deranged.
