Post-Romantic Relationship Reflections

I recently ended a long-term relationship with my partner of six years. We were together since I began teaching at this university, and while we both agreed it was time to move on from each other, there's something that's been bothering me ever since the breakup. Last night, I found myself unable to sleep and started thinking about our sex life. Specifically, I recalled how she often preferred roleplay scenarios during intimacy, which included elements of domination and submission. We always made sure it was consensual and I enjoyed playing both roles, but now that we've parted ways, there's an odd feeling lingering. It feels almost... isolating without the emotional connection these roleplays provided. Is this normal? Do others experience a similar void after ending such a significant part of their life?
