On Monday, the FC Dallas player, 30, shared a lengthy Instagram statement, in which he opened up about a "10-minute lapse in judgment," an alleged "extortion plot" and his decision to commit himself to a "mental wellness program." His post came days after reports that an Instagram user claimed to have "all the proof" of him allegedly cheating on Becky, 26, in February. "To Becky, you have been the light in my life, my strength, who has always shown me unconditional love," Lletget wrote. "Instead of honoring that love every day, I have done the opposite, hurting you, and disrespecting the one person I love more than anything. I am so sorry and know I have to do whatever it takes to earn back the trust and love you deserve." Becky G Says She's Learned That Being Latina Is a 'Blessing': 'So Much More' Than 'Checking a Box' Lletget began his statement by reflecting on the "personal & professional growth" in his life thanks to his relationship with the "MAMIII" singer — which began back in 2016. Becky eventually revealed that she and Lletget got engaged in December. "Yet behind this abundance, there is a reality I've hid from everyone around me," he wrote. "I have struggled with personal trauma and acute anxiety compounded by my own denial, pride and bad decisions." "Over the last several weeks, during a moment I regret deeply, a 10-minute lapse in judgment resulted in an extortion plot. Since this person did not get what they wanted it has now become a public social media spectacle filled with more lies than any truth and false posts aimed at the love of my life, the one person I should never take for granted or put at risk," Lletget continued. "While this anonymous stalker — who I never met, unlike they claimed — had an ultimate goal that was not clear, for me, it has been a wake-up call. The loudest alarm of my life."

Tommaso Boddi/WireImage He continued, sharing that he "can't keep running from demons" and knows "any actions made that put us here should have never happened to begin with." "Pushing right up to the very boundaries of lines that should never be crossed only hurts me and the people I love the most," Lletget shared with his followers. Before closing with his message to Becky and his FC Dallas community, the soccer star wrote that "this past week of chaos & pain has forced me to face the consequences of my actions, my fears & my lapses from the past." While Lletget wrote that he has "half-heartedly been participating in therapy knowing I have deeply rooted anger and mental health issues that require the same commitment and treatment that I devote to my physical well-being," he also revealed he'll be making changes. "If I am the man I aspire to be, I have to do better. I have decided to commit myself to a mental wellness program to work on the parts of me that deeply need healing." Reps for Becky G and Lletget did not immediately respond to PEOPLE's request for comment. Who Is Becky G's Fiancé? All About Sebastian Lletget Sebastian Lletget and Becky G.
