A Canvas of Silence

I've been with my partner for five years now, but lately, I feel like our intimate moments are more about routine than passion. He's always tired after work, and we rarely explore new things together. The other night, I tried to introduce something a bit different, something that might rekindle the spark, but he wasn't interested. It made me question if there was still any fire left between us at all. How do you keep love alive when the flames feel like they're dying?
