"Is it love yet?"
Every time I hear of a longstanding marriage, I am reminded of Cathy and I when first married. My boss and his wife of 12, then13, 14, 15, 16 years,,, would ask us at every anniversary if we thought it "was love yet."
We would laugh and emphatically say "YES!" and they would both give us a smirking smile. "wait until it 12 years and so on.
For the record, he was a cheating asshat. She was the patient forgiving wife. They lasted 17 years.
We are coming up on 50 this May 10th.
"Is it Love Yet?"
I have a new answer I'll bet applies to you and yours....; Always has been love. It takes every day, not every year.
Congrats on your happiness together.
