The couple had a long-distance relationship for one year, constantly exchanging messages with each other. The pair started talking when Gabrielle first made contact with Nathan after coming across each other's usernames through humour website Ticklr in June 2014.

"The first snap ever was from myself to him, and it said 'Hello fellow Ticklr!'

"It was just a black picture though, we were both quite cautious as to what we sent when we first met as anyone should be when meeting new people.

"His first message was an actual picture of himself sitting up in bed as it was very early and I had woken him up. He responded in the same way saying 'hello fellow Ticklr!", Cake decorator Gabrielle said.

They began talking after that and started dating later. Graphic designer, Nathan then proposed to his girlfriend on Skype, though he hadn't met her in real life.

"Technically I proposed twice, once over Skype, and once in person eight months after we met.

"The first time I pushed the camera away, got down on one knee and asked, to which she said "yes".

"I sent her a diamond ring for Christmas that she wore," he told student newspaper The Tab.

The couple made it official on September 17 at Gabrielle's late grandmother's home in Washington.

"I found her stunning, and fell in love with her then and there - though I still don't really believe in love at first sight.

"I remember noticing she was incredibly small. I knew her height - 5ft 4 - but being able to actually see and feel it made it real," Nathan spoke of the first time they met, adding that his parents aren't really supporting the union and are doubting the future of their marriage.

"It was difficult explaining to both families that we were a couple. Even harder when I proposed.

"Generally my family supported us, but had doubts that anything would ever last between us, telling me not to "get my hopes up" as she may not be who I think she is.

"My mother met her several times over Skype and she eventually came to terms with me moving away with someone, who in her mind, was a stranger," he continued.

"I think being apart for so long really made a very strong base for our relationship, based entirely on the companionship of the other person and not just about having someone around.

"It made us very close and has made things a lot easier because we relied on each other completely emotionally and were able to build on that," Gabrielle said.

"We never really had a chance to take things slowly.

"It was never a question of how fast or slow we should move in together, we just did because that's all we could do. It's not like we could stay over for a weekend," she continued.

Nathan said he is very happy with his marriage and his decision to move to the United States to live with his wife.

"I would move anywhere for my wife. To experience more happiness and finding someone that thinks, feels and lives how I do is something I will never regret," he said.
