That’s business.
You’re either growing or you’re being left behind.
If you pull away from your business partner, you must be ruthless.
Cut her loose.
That comes with lots of unnecessary pain and distraction and expense.
So do your best to keep your partner next to you, in sync, on same page.
Help her grow.
Don’t put yourself in a position where you must leave her behind.
But if it happens, it happens.
Only one option.
