Is it normal to loose Attraction to your spouse

Hello everyone I 32m have been with my wife 34f we have one child after having our child we just kinda stopped having sex in the last 8 years we have had sex maybe 5 times, tonight my wife tried to initiate and I just couldn't, I'm not sure when it happened but I'm no longer attracted to my wife ( I'm not saying physically) is this normal what do I do now ?

I'm not even sure when this happened I honestly can't remember the last time we even kissed
