Yoh my daughter knows all my names. From my nickname Saly, to my traditional name Kufanga, to my colonial name Sylvester. And she's only 4 how did we get here???
Your partner is human.
Give them space.
Let them exist outside of being your spouse/parent of your offspring.
If they have interests or vocations that you aren't interested in, enable them the time to feed "their thing"
Do the same for yourself.
Be an individual, too.
