You are absolutely correct.
English is very poorly served by our having only a single word for the many aspects of “love.”
Love is a feeling and an emotion, certainly, but also it is (or can and should be) an attitude and a commitment. The latter two can keep you going during the periods when the first two falter.
Very few people will live together for a lifetime and always feel “in love.”
Mrs BN (”Luscious Babe”) has been married for 41+ years to “a 12 year old, trapped in a 64 year old body!”
Her “mighty hunter, fine figure of a man” is no longer either, but she still loves me! And vice versa!
She was 22 and I was an old man of 23 when we married. However, I’d been through a tour with the Marines in Vietnam and she was a senior in college and one of 8 kids.
We made a vow “before God and these assembled witnesses”, including families.
‘Nuff said!
