My dsc mum moved to be closer to their school as she used to live 30 mins away, we have a 50/50 care agreement they are 12 and 13. Their mum loves her children but unfortunately she always has been unstable sometimes wants her dc and then doesn't. She has a history of abandoning them and causing trouble. We know she is in a lot of debt etc and wondering if this is why she won't give her address out. My dp has asked her but she just ignores him, then he had to fill out a school form and it needed the mums address. The dc claimed they didn't know, but they looked uncomfortable and went a bit red so dp didn't push them as it's not their fault. Eventually their mum gave an address of her boss said that's where she's registered 😳. It just feels wrong the dcs are told to lie and she won't give their dad the address or the school. It's horrible seeing the dcs lieing to their dad even though it's not their fault but they shouldn't be put in that position. What do people think of this, should dp push his ex for her address or just leave it?
