I saw what you said about being indifferent to an ex. But what if your ex has never responded to that. What if it takes sheer fucking embarrassment, or a smashing of his precious car, or face. What if you never see you ex anymore, and never got the revenge you should have months ago?
Your ex never responded to indifference because you never showed him any. You aren’t capable of indifference until you let all that negative shit go.
Do it, babe. Just let it go, for your sake. You’re sounding a little crazypants.
