Listen to Robin Thicke on iHeartRadio

(Yahoo!) - Robin Thicke is not ready to walk away from his marriage — as he told the audience at the Patriot Center in Fairfax, Virginia, on Thursday night.

Taking the stage for the first time since he and his actress wife, Paula Patton, announced their separation, the crooner talked about his marital problems and dedicated his performance of "Lost Without U" to her.

"For those of you who don't know, my wife and I got separated a few days ago," the "Blurred Lines" singer told the crowd. "But I want everybody here to know: I'm trying to get my girl back."

In a YouTube clip of the moment, you can hear someone say, "That's brave," as he gets candid with the crowd, and the audience screams wildly when he says he's not giving up on his marriage.

Thicke, 36, continued to talk about his marital strife, recounting a conversation he had with Patton, who is his high school sweetheart.

"She told me, she said, 'You should go out there and tell the truth, ya know? You should tell them that you're trying to get me back," he said with a laugh. "She's a good woman."

After taking a moment to wipe his face — and adjust his hair, natch — he gave a hoot of relief.

"It's hard to say it in front of everybody," he admitted. He then asked the crowd to help him with the next song. "If you have somebody with you tonight that you love and you appreciate, hold on tight to them. Take care of them. 'Cause I want to dedicate this song to her. I wrote this about her and I need your help to get me through it. Let's do it."
