Love your SO but not InLove

I am curious how many of you are in this situation. I’d love nothing more than to be in love with my SO. I know I will be criticized when I say I try very hard while have an ap but I do. And I have tried without an AP as well for years only to be drawn back to this for the full passion and depth of a true in-love feeling (which is also very rare to come by even in this dynamic, I was one of the lucky ones)

Be kind: How many of you love your life and companionship is great at home but you’re lacking the chemistry? Am I the only one? Were you able to fix this? Is an affair level passion not possible in a conventional relationship? Am I asking/hoping for too much?
