I made the worst decision of my life. I chose to be unfaithful to Lily, and caused her an excruciating amount of pain. I'm incredibly sorry for my selfish and irredeemable behaviour. I betrayed her trust and love for me, and for that, I don't know if I'll ever be able to atone for it. I'll be taking an indefinite hiatus from content creation to reflect and spend some time alone.I'm sorry for the people I've hurt in all our communities, I'm sorry for the friends I let down at Offline.TV, and most all I'm sorry for hurting you, Lily.The identity of the person Albert cheated on Lily with has also come to light and has been revealed as Sarah Lee, who goes by the name @avocadopeeled on Twitter.She too has released a statement on Twitter expressing her apologies.I'm sorry. No one deserves the level of pain I caused, especially not Lily: someone who has only shown me kindness. My choices were immensely selfish, and the levels of betrayal go beyond repair. She did not deserve to suffer like this. Nothing I write could ever be enough, nothing I say could possibly change anything. It will never be enough. Therre is only reparation in who I choose to be from here on out.I will be taking time awat from the public for self-reflection.I'm sorry for the extreme hurt I've cuased to everyone in the communities, to those who I could once call 'friend', and to Lily most of all.I'm so sorry.Have something to tell us about this article?
