Here’s a revised version in proper English:
"Letting you go was not my desire; I did it only because it was what you wanted. I never wished to say goodbye, but I understood that it was necessary for you. My heart ached as I made that decision, fully aware that it was not what I truly wanted.
I held on for as long as possible, hoping for change, hoping you would choose to stay. Ultimately, I had to respect your wishes, even though it shattered me inside. I let you go because I loved you enough to grant you the freedom you sought, even if that meant losing you.
It was not an easy choice, and it continues to be a struggle. However, I genuinely hope that, wherever you are now, you have found the peace and happiness you were searching for. Please know that my heart didn't want this, but I made that choice out of care for you."
