"Because I don't care about any of that.  I don't care if you think you're not the pony I fell in love with anymore because I know you still are."  She moved in closer, not breaking her stare, "I spent so long just thinking that this was my fault.  There were nights I just stayed up thinking about what I might have done wrong.  Then, I'd get angry that you left me and for a while I hated you.  But," she moved in even closer, her face almost touching his, "I hadn't even thought about you.  Even when I talked to Rarity or AB, I never asked about how you were doing.  I just assumed you were fine.  Hearing what you had to deal with though… I can't believe I was so selfish.  Even when I got your letters, you seemed like you were happy.  Hearing that you almost killed yourself… I'm not worth that.  Nopony's worth that.  Now though," she moved closer still until she was right next to his ear, "I just want to say I'm sorry.  I can't even imagine how hard this was for you."  She could feel him shaking from the emotional strain as she continued, "Yet, I felt the need to drag this out into the light.  I can't even find the words to begin to convey how sorry I am about that.  But maybe," Sweetie leaned in further and kissed Button on the forehead, eliciting a surprised gasp from the surprised stallion, "that will be a good start."
