Has Robin Thicke given up trying to woo back his estranged wife Paula Patton?

After multiple public apologies and an album dedicated to his longtime love, it seems the R&B/pop singer may be ready to face the music.

TMZ reports that Thicke put their one-time Los Angles home on the market this week. And insiders say Thicke has started telling people he's done trying to reconcile their marriage and is ready to move on, though he will reportedly wait for Patton to file for divorce first.

When asked what it's been like to watch his marriage fall apart, Thicke, 37, told CBS News, "It's been a very humbling year, to say the least."

Patton has kept mostly mum on the issue, but told Vanity Fair earlier this year, "We've known each other since we were teenagers. All I can tell you is there's a deep love there -- always was, and always will be."

Thicke and Patton got married in 2005 and welcomed a son, Julian Fuego Thicke, in April 2010. The couple split in February -- and ever since, Thicke has tried to win Patton, 38, back.

But maybe he's sung his last song?
