A heartwarming video has emerged of a man kneeling down to propose to his girlfriend although necrotising fasciitis left him with limited mobility in his leg.

The footage, shot on January 27 at Saint James Airport in Canada, shows the couple reunited after a spending a week apart.

After greeting her, the man kneel down to ask his girlfriend to marry him.

As she realises what is happening she can be seen jumping up and down with excitement.

"When our lives crossed paths two years prior, he was in the hospital with a serious case of necrotising fasciitis in his leg and came within hours of loosing his leg or worse, his life," she told Newsflare.

"The mobility of his left leg was very poor, he could barely bend his knee and his ankle did not move. Still on IV antibiotics at home, We started working with him at the gym."

"The surgeries had taken more then 30% of the muscle out of his leg," she added.

"He confessed the next day that the week I was away, he practiced getting down on one knee and getting up without falling. This little gesture left me in tears."

After a week away, my boyfriend of two years surprised me in the airport at 2AM and handed me a dozen roses. After our exchange of "I've missed yous", he proceeds to tell me he has realized he does not want to live one more day without me. Throwing my coat on the floor I looked at him puzzled and then he dropped to one knee and proposed. Too see my man on one knee was more then we could have ever asked for.

When our lives crossed paths two years prior, he was in the hospital with a serious case of necrotizing factitious in his leg and came within hours of loosing his leg or worse, his life. I worked as a nurse at the hospital he was admitted to. A few months later, and multiple surgeries for him, he was discharged and we went out for coffee once he could walk again. The mobility of his left leg was very poor, he could barely bend his knee and his ankle did not move. Still on IV antibiotics at home, We started working with him at the gym. We finally got his knee bend to 90 degrees. We never thought he could propose on one knee like everyone else as the muscle tone left him with very little support. The surgeries had taken more then 30% of the muscle out of his leg. He confessed the next day that the week I was away, he practiced getting down on one knee and getting up without falling. This little gesture left me in tears. He is my world. September 23rd 2017, we got married and life has never been better.
