She looks like a street walker. She looks like one of the most stereotypical examples of a dangerhair that you could ask for. She met him on Tinder. He literally married a tinder thot. Just because there's an exceptions to the rule, doesn't mean finding your wife on Tinder isn't completely fucking laughable. Especially one covered in body mods.
She is neither a good wife or a good mother. Unless further information says otherwise, she is destroying her family because they've "grown apart". Except that's every marriage. That's why marriage is a journey. Sure, she did stay with him through some awful times. She is choosing now, to destroy her family though. She is choosing now that they've spent thousands of dollars on IVF. She is choosing now to divorce after they have two high maintenance children. She could've simply divorced him before having kids, but chose not to. She waited until it's the most destructive time possible for both Dankula, and her own children.
On Dankula's end, he could've dumped her at any time. It doesn't take a genius to figure out that maybe dragging her through the mud with the shit with the dog and their financial troubles wouldn't take its toll. That kind of stuff tends to not bode well for relationships. Even if she insisted on staying, he could've spared her all that stress and trouble and chose not to. He also could've simply, not married a girl off of Tinder. Again, that's before we open the femboy can of worms. I wouldn't be surprised if information does later come out that justifies Sue's actions either. But hey, Dankula makes bad choices and that's why he's here.
