Dean Sheremet Going Through a 'Very Difficult Time'

"Thanks to everyone for all the support through a very difficult time!" he tweeted on Saturday.
The message was only Sheremet's second since a post on March 18, when he posted the words, "I love my wife!!!"
Saturday's message comes just one day after PEOPLE reported that the couple, who married in 2002, are no longer living together.
"Le and Dean have been separated for quite some time now," a Rimes pal said, "but they're continuing to try and work through their relationship."
