Ex DH and I have never argued about money. I've always said he's a really good guy and we'll always be soul mates etc etc. We'd been married for 30 years. We have four grown up children. 5 years ago we split up but stayed living together (in separate rooms) and have been roundly praised by everyone about how amicably we've dealt with this. I've had another relationship (with a woman). He's now on his second relationship since splitting and they seem very serious. Our divorce didn't involve lawyers as we've always thought we'd continue with the massive respect and love for each other we've always had since raising four children together.
But now he's like somebody else. He's weird and cut off from me and barely civil any more and I have no real idea why. It coincides with him getting serious with his partner.
Long story short - I now feel vulnerable. He's always said he'd lay no claim to my pension or inheritance and I've said the same to him. He always said when we finally sell the house (it's on the market) it can be a 65/45 split in my favour as I shelved my career which has flatlined since have children while his has soared. He now earns ten times what I earn.
So I feel I need it in writing that he won't come for my pension or my inheritance. I never thought we'd need to do it this way, but I no longer recognise this man so don't feel I can trust him.
Is there an easy and inexpensive way of getting a financial order? Or have I really blown it by getting this amicable divorce and being too trusting?
