Talking to boyfriend about divorcing ex

Priscilla
My boyfriend and his ex (baby mama) haven't filed for divorce. They've been separated for 5 years. He's saying it's the money and his daughter. My mom who has gone thru a divorce said its just an excuse. We've been dating for 2 years. I told him today this week I want to talk to him about it. We usually always fight when it gets brought up. I told him I want us to be calm and not get heated. I'm trying to figure out what's the right things to say and ask. Please help!
