Your rage towards the other person grows. You criticize them in front of your friends, online, and to anybody who will listen. After that, you make a relationship pact. You tell yourself that being alone is better.
You end up behaving like you don't care because you don't want to express how hurt you are over being rejected. You cover up your true emotions with sarcasm and insults.
You develop an obsession. Observing them on social media. You send them three consecutive texts. You try to elicit responses from them. You work to find resolution. You make an effort to reconcile.
You find it difficult to move on, and you're not hesitant to tell them as much. For them, you'll get down on your knees. Because you are unable to recognise that you deserve better, you will beg for them.
You start looking for someone else right away to make up for the hole in your heart. You text your ex-partners. You have sexual encounters with people you aren't even particularly attracted to.
To feel better about the one who chose to ignore you, you make out with the first person who finds you attractive. Instead of looking within, you seek confirmation from elsewhere.
Because you are blind to their imperfections, you hold yourself responsible for losing the other person. You are solely accountable for driving them away. You believe you made a mistake.
