You could have that kind of friendship with exes but only as a time passes. It’s uncommon to have good friendship immediately after divorce. I’d say at least a year to a few years need to pass. After my divorce I only spoke to my ex if absolutely needed. We are friends now and certainly would contact each other to express sympathy or share good news etc not right after divorce. It’s important to allow healing to happen

Sorry about your father. I cry large portion of the day on moms death anniversary and I am not even a crier. It just hits you. It gets better but it still comes like a wave
