I Loved Someone That Didn't Love Me

It was a long time ago. We were goofing around but we agreed to be in a relationship. There were years we didn't see each but we kept contact with each other with love letters (which is sooo old school these days). After we started meeting again, I tried to hang out with her a lot but with her family and everything was so serious that we only met at school or at parties or other occasions. Even dates weren't allowed until we were at high school. We never kissed or had a romantic time. The closest thing we ever did was give a hug. I agreed to her wishes because i respected her. I guess its the way of people saying "Taking things slow". We had an on and off relationship after a few years. She kept making up ways to end it but she was being silly and all so i tried to make her understand and she did for sometime. I don't know what happened next. Maybe I was impatient. The 9th year of our relationship where we were in high school, i sent a wrong message to her which had things written about her but they weren't wrong nor personal. Only what i thought about how things are going with me and her. After a few days she sent a text and a part of it said this ---> " I don't think I love you anymore like i used to ". That broke my heart. I lost my mind few days. After all those years of waiting and being a good boyfriend for her I ended up nowhere. She didn't literally say it maybe because she knew i'll be hurt so i broke up with her and never spoke to her ever since. Its been 6 months since then. Not so easy to forget about her because everything reminds me of her :
