So here is my story,

Freshman year of high school I met a girl or rather I heard her laugh, turned around and saw her. From the instant I saw her I knew that I wanted to marry that girl one day. As a shy and immature freshman I did absolutely nothing about that heck I never even spoke to her truly for three years. I would text her about once a year just to say hi but nothing more. Then one day I messaged her out of the blue at the beginning of senior year and asked her out. She said yes, and we dated for almost four years. We had a great time talking and what not and even now still consider each other to be our best friend. For the majority of our relationship, we were long distance due to college. She decided to break up with me during the Thanksgiving Holiday a few months ago. We still talk every now and then and we are both trying to move on. Here is the thing, however, I still have the same faith that I will one day marry her the same faith from the day I first met her. I still love her deeply and although I am working on bettering myself for myself (due to depression, anxiety, and physical health issues) I still feel the same. I know she doesn’t feel the same way or look at me in the same way which she once used to. I know she is changing and isn’t the same person and that I’m not the same person and yet, I still have this belief. It’s odd and it’s true and I don’t know what to do. I have dated other people before I managed to ask her out but the feeling never went away, it just sat there simmering in the back of my mind. I could use advice.
