Love, who captained the hosts at the Medinah Country Club in Georgia, saw his side squander a 10-6 lead going into the final day as the Europeans staged one of the most remarkable comebacks in the competition's history.
"I'm still not sleeping well. I still think about things. We didn't win, so I accept that," said the 48-year-old.
"If I could do something over again, it would be more getting guys thinking about how to play singles and maybe the pins needed to be easier or harder."
Love was speaking ahead of the McGladrey Classic in Georgia, which starts on Thursday.
