I miss my ex

I don't know why but I miss him I miss everything about him we used to talk all the the time and one day he just decided to break up with me. I think it's my fault, but we still follow each other on Instagram we still kinda talk not really but I miss him he even said he missed his ex on his notes[im his only ex btw he never and I mean NEVER dated anyone before] I just miss my princess so much [he hated when I called him my princess]
