Write a small paragraph to a person who I used to love and I thought he loved me but he doesn’t anymore. Write it like saying that I want to know if I didn’t anything to make him fall out of love and if I did to tell me. And that it’s okay to not reply to this message but to at least notice it and read it

Hey there, I hope you're doing well. I wanted to reach out and ask if there was something I did that made you fall out of love with me. I thought our connection was real and strong, but it seems like things have changed. I just want to understand what happened, so if there's anything you want to share with me, please feel free to do so. I understand if you don't want to reply to this message, but I would appreciate if you at least acknowledged it and read it. Take care.

Write it informal

Hey,

I hope you're doing alright. Just wanted to ask if there was anything I did to make you stop loving me. I thought we had something special, but it seems like things have shifted. If there's something you want to talk about or share, I'd be open to hearing it. No pressure to reply, but it would mean a lot if you at least read this. Take care.
