Donovan admits a new deal, however, will be considered.
"Everton was a fling that grew into a full-blown affair. I do think about them because they really stole my heart when I walked into Goodison Park," he told ESPN. "Everyone was so unbelievably welcoming, from Mr Moyes to the tea lady. I have such affection for the club.
"But I've struggled with motivation at many points in my career. I've had times where it all came easily but there have been stretches where I have questioned it.
"I have some selfish things I need to do, and I have some things to work out. While most soccer fans think a player's life is easy as we just seem to play soccer all the time, they don't see how many milestones I have missed with my family.
"My family want me to either play and be happy or else to have their son and brother back."
