Some interesting quotes from the story:
"There have been plenty of times where I had to fight hard against jealousy, especially in the beginning. I think most of the times that jealousy has taken over, it boiled down to me feeling unimportant, or left out of the loop. Now, when something bothers me, we talk about it quickly and agree on a path forward that works for everyone involved."
I think that one is really important. Jealousy happens when they need to talk more about it, and make sure both are included.
