I feel like I'm the reason why you are angry, frustrated or sad. When you don't text back, it feels like you are less interested. Sometimes when you don't talk, I look at the previous text, wall post, chats we had. They make me miss you more, they remind of of the good times we had, importantly they make me happy and bring tears of joy to my eyes. Hiding my negative thought from you is to keep you smiling, sharing something funny is what I'd do to keep that smile alive.
