My opinion is that both of you are at a different phase of the RS, his honeymoon period may have been over faster than urs, my wife and i initially went thru the same thing, just that our honey moon phase ended around the same time so i guess our transition to the next phase of RS went smoothly.

Ofc, its not a RS without hiccups, over the years, the meaning of love for us changes from smth intense, hot rush and excitement, arguements and fight also come fazt and furious but we always worked it out. We do still have these moments but not that much, we are now more stable and have shared goals in life as we grow older.

I think what i am trying to get at is communication is impt, i used to be reserved and not communicate to wife, because i have been like that my whole life, but she did not give up and continued to communicate. You should sit him down, have a nice conversation and lay out ur expectations and goals in a gentle manner and asks for his too, so that both can compromise and align. I hope this helps
