It must be tough leesa, I'm so sorry you are both going through this. And I am so sorry to hear about your mum. I think its a fair call for you to tell her to get her own copies. It sounds like she's not making life easy for you guys or for her children. But the thing is even if you choose not to fight now, one day the children will see it for what it really is and who knows how you will both feel in 12 months time.

Goodluck!
