How lonely is it to move forward while your partner is stuck in place? Answer: fairly. You want them to move forward with you but their stuck and you don’t know how to free them from the quagmire. How do you free them from the muck slowing them down?
You can’t. All you can do is encourage them to free themselves. Whatever muck they’re stuck in, they have to dig themselves out of it. You can give them a shovel or a rope but they have to do the digging and pulling.
Give them the best shovel you have and cheer them on as they start to dig. Celebrate their progress. Cheer them on. They’ll need it.
