If your ex moved on fast
They cannot stand being alone with their own thoughts. They hate themselves. They have to focus their attention on another person to distract them from their own misery.
They are consistently plagued with pain. Nothing is ever enough. They’ll throw away any used toy for a shiny new one like it’s nothing. Burn bridges left right and centre, because they are never satisfied. Ever. No matter how many bodies, compliments, memories, gifts, they get they will always want more. Those people have an endless void inside them and they’ll never experience true meaningful love and connection.
Let them. The biggest lesson in life is let people do what they’re gonna do, eventually their actions will make you feel sick and the more they do the easier it’ll be for you to move on. Nothing you can do can stop their pain, it’s their internal misery they cannot escape and that should be closure enough. They avoid discomfort for temporary pleasure. Key word being temporary.
They will always hurt until they decide to change.
Take it from me who was once - that very person.
I thank whatever celestial force is out there that gave me the self awareness and maturity to fix myself and find my heart.
You will find love again, I promise you that.
P.s. None of this is to say that your love wasn’t real, that the relationship was not real. It was real, for you. Every moment was important, every word you said to them was genuine. The love you shared was never wasted. People’s actions are a reflection of themselves and not you. Never regret the love you had for them because at least you can love.
