Chutney, another lurker here, wishing you well.
Can I ask whether your shitty ex's new partner has a house??
I just ask because my own sister in law (h's sister) had a very acquisitive cheating ex.
He left with OW after he had beaten her up for daring to object to his affair, and after the neighbours came to her rescue and called the police.
He too consulted heaps of solicitors, so she couldn't find one easily.
What he did next was truly staggering.
She fled for that week to her sisters, because she was understandably upset and needed company and some help with the kids whilst she absorbed the shock. She was also a bit worried for her safety. So he very prompted moved his OW in, who, can you actually believe, chucked out alot of her stuff and repainted her bedroom and bathroom!!!!
It took months to get hi out again.
I just think that men like your ex have absolutely no scruples, and that they can be trusted in no way with property of any kind.
