A man who returned home to find his girlfriend in bed with someone else had a bizarrely calm reaction to his partner's alleged infidelity .

Duston Holloway, from Emroy, Texas, was greeted with the heart-wrenching sight of the woman he loved 'passed out drunk' next to a shirtless man in the couple's bed.

But instead of causing a huge argument, Duston calmly took some photos of the pair, and even posed for a selfie as they slept.

He then shared the images on Facebook, ensuring the whole world could find out.

In a status, alongside four images, he wrote: "When you come home to another man in your bed with the one you loved! Good men deserve good women."

The pictures show Duston's girlfriend, who is wearing a t-shirt, asleep next to the shirtless man.

When one Facebook user asked Duston if he had woken the pair up, he said that he wanted to "kick his a**".

He added: "But I calmly just took selfies and walked like a boss. I did tap her to wake her up but she was drunk as a skunk passed out.

"I was gonna ask if I was gonna have to sleep in the spare bedroom and what kinda breakfast the dude liked."

Since then, Duston's pictures have gone viral, and many social media users have praised him for the way he dealt with the situation.

One Facebook user wrote: "Everything happens for a reason, good on you for just walking away. Good luck for the future."

Duston later added a thank you message to every one for their worlds of support.

He wrote: "Yesterday, I thought my world had [fallen] apart, I was heartbroken to ever [have to] witness something like that, but with the amount of support from FB and family and friends, I want to personally thank each and every one of you.

"The world ain't as bad as we think."
