The hovering
The friction tends to arrive when the care tips into watching too closely. The wanting-the-partner-to-flourish becomes wanting-the-partner-to-flourish-now, in this specific way, with this particular shape of opening. The reach means it well, but the partner senses the watching, and the watching itself becomes pressure. What was supposed to be conditions-for-the-partner becomes a soft expectation the partner has to meet. The flowering they were going to do anyway gets converted into a performance for the attention being paid.
What helps
"I love being with you. There's no shape this has to take." What helps: practicing the discipline of not knowing where this is going. The hovering happens when you have a half-image of what the partner's becoming should look like. Letting go of the image, staying curious rather than expectant, keeps the conditions open rather than directional. The partner's becoming belongs to the partner. Your gift is being the room, not the choreographer.
