Pretty much that.
My ex whom I was with for 3 years and I used to discuss potential names for our dcs should we ever have them but we subsequently broke up before we had dcs.
I'm now with someone else and wanting to use a name that my ex had suggested as I just love the name. My current partner doesn't know that this name was from my ex, he just thinks it's a name I like and therefore why not call our soon to be born dd that name. I wonder if I'm being actually misleading or mischievous by using the name from ex? Am I over-thinking it?
