The spark rarely returns by waiting for it. It fades when you stop seeing each other and start seeing the routine, so the way back is fresh experience, not more pressure. Do something unfamiliar together, side by side, where you are both a little out of your depth: a class, a workshop, anything that makes you laugh and pay attention. Add touch that leads nowhere in particular, so closeness stops carrying a demand. Build small moments where you can miss each other, then meet again. Curiosity is the whole engine here. Start with one thing this week, and keep it.
