Just that really. DP loves me, but somewhere after a couple of years I became more of a very dear, sibling-like partner who can provide comfort in times of stress and good company on walks. Our sex life dried up as did any romantic gestures. Date nights are just meals. There’s no effort to ignite a spark. DP has been blaming a series of stresses at work, however think it just boils down to not being seen as a romantically desirable. Not ugly - just the same way you wouldn’t fancy a sibling or parent.
Obviously there’s a lot of love - just no spark. DP says that’s it’s natural for it to go once you’re middle aged and it’s not a problem for them. I suppose I’m just looking for a sense check.
Edited to add- for context we’re both in our early forties, together for four years, divorced, no kids.
