Let me begin by saying, what happened is not your fault. Really. You have ran through the situation at least a million times and have questioned every decision you made, but this is the thing: what happened is not a result of something that you did, something you said, or something about you. What happened was simply going to happen because that was meant to occur.
Whether the infidelity happened because someone was unhappy, someone made a wrong decision, or someone does not actually know, it happened. But just because something negative happened, that does not mean your worth is defined by the event. Someone's decision to hurt you does not reflect your character in any way.
But the worst part about the entire situation is that going forward you question every person's ability to be loyal to you. If the person you trusted the most, the person you bent over backwards for, the person you gave your heart to can throw it all back at you in a second, then what is saying that anyone will not do the same?
And from here forward you are going to give 150% into every possible relationship you have, but it still will not feel like you are giving enough. You are never going to feel like you are enough, and internalize that pain with everyone you interact with.
You will hold on with the tightest grip to people who are meant to be let go. You accept the worst treatment from others because that is what you believe you deserve. You constantly think that people will change because deep down you always want to believe that people are honest, pure, and genuine, even when they hurt you repeatedly.
And you are going to push people away because you are too scared to find something that is real. You are afraid that they will hurt you, so you eliminate the option for them to. You run away because that is what is safe and you can avoid feeling like you did before.
You will accept the love you think you deserve. And that love is far less than what you deserve. You will tolerate lies, excuses, and mistakes because you just want to be accepted by someone.
But why? Why have you given up on yourself? You know without a second that you will go to the deepest depths of the ocean for someone, or climb to the highest mountain to make someone smile, so why do you deny that you deserve that yourself?
You need to know that you deserve to be treated with all of the kindness in the world and to be loved with everything that someone has to give. You deserve to feel like your tallest wall has finally broken down because you are around that special someone. You deserve to have your soul take flight when you interact with them because there is simply no safer place for you. You deserve to feel like a diamond, pearl, or ruby--the most prized possession in this world.
You deserve someone's absolute best, and nothing less. And just because someone made a poor decision by making you feel like you should be treated less, you still are worth that love from someone. You may feel broken, but you are not. You may feel worthless, but you are not. You may feel alone and helpless, but you are not. You, just as you are, are good enough to be given the world. And nothing less.
