They began dating and eventually moved in together in New York for a year.
But Martin said everything changed when Yanet decided to go back to Mexico City to pursue acting and modelling and return to her job as a weather girl.
"I supported her decision," Martin said. "She wanted to be a supermodel actress - chase your dreams, life's too short."
"I'm playing Call of Duty full-time now and she wanted to take her job opportunity. I didn't think it was going to be that difficult."
But Martin found it harder to do a long-distance relationship the second time around because he was spending so much time playing the video game.
"Back then it was a lot easier for me to go out and see her," he said. "But now I have obligations."
"I'm on a contract. It's not like I don't want to do this, this is the career that I want."
"I want to win a ring, I want to win a world championship, what I want in my life at this very moment is to compete in Call of Duty because I love it so much."
"I'm going to do whatever it takes to be a champion."
Martin said he had to pick his "poison" of what he wanted to spend his "time and focus on", and the video game won.
"There's only 24 hours in a day and I just didn't have enough time to do what I needed to do," he said.
Garcia, who has 6.5million Instagram followers, has since thanked her fans for their support during the break-up and even shot a few subtweets at her former beau.
After writing that she was heartbroken, Garcia retweeted a tweet that read: "Respect yourself enough to say, 'I deserve better'".
