Does it actually exist ? I’m separated and trying to be really balanced about providing money and support yet I feel like she treats me like a cheque book. She spends too much in my opinion. She looks after our two young kids so I accept she needs funds for that. I had assumed we would be able to work things out money wise but she makes it very hard. I’m left feeling that a legal financial agreement where she gets a fixed amount is the only way forward … any thoughts ?
