For a while, standing at the finish line of the Boston Marathon in 2013 was the worst thing that happened to survivor James Costello, but it quickly became the best.

Costello was blown up in the terrifying attack but the resulting agony saw him meet the love of his life, the nurse who cared for him in hospital, and the couple tied the knot this past weekend.

The 31-year-old wed Krista D'Agostino in a ceremony and reception donated by local business.

In front of some 150 family and friends at Boston's Hyatt Regency, the couple said 'I do.'

The couple became close as Costello struggled through months of surgery and painful rehabilitation following the April 2013 bombing.

Though he didn't lose a limb like many others, he was left with painful wounds throughout his body.

A now-iconic image shows Costello staggering down Boylston Street in the aftermath of the blast with his clothes in tatters.

The bombing left three dead and more than 260 injured.

D'Agostino, who worked at the Spaulding Rehabilitation Hospital, nursed him through grueling skin graft operations and exhaustive physical therapy.

'She hates when I say this, but I'm actually glad I got blown up ...I got her,' the survivor said on the 'Today' show in December.

The newlyweds are now heading to Hawaii for a relaxing honeymoon.

The nuptials come a few months after another Boston bombing survivor - Costello's friend, Marc Fucarile who lost his right leg - wed his high school sweetheart, and achieved his goal of walking down the aisle.

Fucarile was watching a friend take part in the marathon with four boyhood buddies from Stoneham, Massachusetts when the bombs went off.

After the first bomb detonated, brothers Paul and J.P. Norden huddled with Jarrod Clowery, James 'Bim' Costello and Fucarale, not realizing they were inches away from the second device.

When it exploded, both brothers and Fucarile lost a leg, while Clowery suffered burns and shrapnel wounds and Costello was hospitalized with serious injuries.
