You can wish someone well without giving them directions back to you.

Wanting good things for someone and wanting them back in your life are separable, though they get tangled because kindness feels like it should include access. You can genuinely hope someone thrives while keeping the details of your life to yourself.

If you find warmth returning toward someone you stepped away from, let it be warmth rather than an invitation. Notice the pull, hold the distance, and let both be true. That combination is more stable than it sounds.
