Bicycling COULD be an addiction. Addictions come in all forms (it doesn’t have to be hard corp drugs or alcohol).
Sounds like you have some great ideas to still be able to ride and then have more time for your wife. Early morning rides, etc,etc.
find out what her trigger points are and come up with solutions (could be riding a little less but let’s hope not)
be careful out there in the early morning if you go with that plan
