Liam, I'm sorry for what you're going through. As I've caught up on your sitch, the red flags kept popping up left and right. Your W reminds me a lot of mine. And that's not a good thing in any way.
Welcome to the Reality Distortion Zone. I'm gonna go out on a limb and give my professional opinion on your W: She's a f*cking nutjob. You're not crazy - don't let her convince you otherwise. Imagine you're surrounded by a bubble of sanity that she can't penetrate.
She's completely selfish and has no regard for you. She lies to save her own hide, so do not believe A SINGLE THING she says. If she says it's sunny, bring an umbrella.
I second Gordie's question. It's time to get a L. Do EVERYTHING you can to protect yourself and your finances.
