I’m really sorry to hear of the situation you’ve found yourself in. I’d like to find out a bit more if you would be willing?
Do you think there’s a chance of you both getting back together? Is that something you would want?
What other benefits do you receive?
Does the other person now involved with your ex work and earn a living? What responsibility do they take for your children?
Do you have flexibility around care arrangements for the children?
Have you spoken to your employer about this at all?
Is there a formal agreement for care arrangements?
