I like the sentiment. But abuse aside.
Would you make breakfast for your ex on their Birthday?
I probably would not mind but I think if it was the other way round, if my partner was making if for his ex I would be a-bit jealous.
Maybe it's better for a clean break? Bit to act sensibly infront the kids but then we are all human.
I actually still see my exes daughters ( dd half sisters). My partner is understanding. I don't know whether I would be.
Hmm torn.
