Oh Lord! I really have no words! Sweet Girl, I don't know how you're still standing! But I think there's a lot to be said for the strength that comes with knowing you are right. And from protecting your children. You are strong. Really you are. You've made it this far, you'll make it all the way. I'm sure that WWK feels the same. I am so glad you two have each other in RL! As far as your voice, when I'm under extreme long term stress there are times that I actually get a partial paralysis of my vocal chords. It's only happened a few times and luckily anti-anxiety meds took care of it. Once the stress was over, it went away. Our bodies are just weird, I guess.
As far as OW, the reason she's so ugly is because she knows, deep down, how wrong and evil she's been. The only way she can live with herself is to convince herself that you are the 'bad one'. More fool she, I hope she thinks he's worth destroying her own soul for. Because I don't believe that anyone who cheats, lies, and does dirt like she has comes through it without real damage to their soul, spirit, self, whatever you call it. Same for him. Think about it, at one time he was a decent husband (well, I think he was) and look at him now. Don't tell me that his spirit or consciousness is undamaged and whole. No way. He's damaged down to the bone. So is she. So as hard as it may be for DS to understand, really, I think it's better that he sees as little of his 'father' as possible.
With all the shit he did that got him arrested, do you think that you might now qualify for legal aid? I know that abuse has something to do with it and if you have a restraining order maybe that might qualify you. Also the fact that OW has family members from whom they are probably getting free or 'off the books' legal advice. I'd certainly call them (or whoever you'd call) and ask. It can't hurt.
I'm so sorry for the loss of your dear Auntie. Just hold on to your memories and remember that no one is ever really gone as long as our memories of them make us smile. And I know you must have many wonderful smile-filled memories of her.
