What does a promise ring really mean?

On January 4th I had my year anniversary with my boyfriend. We practically lived together. We stayed at each other's house every night and spent the time together we had when we weren't working or at school. It was really nice and we were really comfortable together. We made plans to move in together when I graduated. He would follow me to college and get a job roofing wherever that was. It was a commitment we both wanted, which is weird since we're young, but it just seemed to click for us.

On our anniversary he got me a promise ring. I was really surprised. He normally sucks at keeping secrets, but I didn't know it was coming. the ring was very beautiful. It was amethyst, which is bright purple, and my favorite color.

Probably about a week ago our relationship ended. It was out of nowhere. People made up a lot of rumors about both of us, everyone was fighting to keep us apart for some reason, and we didn't know what to believe. It was really hard. We both fought to stay together, but when people are saying a bunch of lies to you all the time, you dont really know what to believe. He was my best friend and the only person in this world that I could fully trust. I loved him a lot. Sometimes I just give in and talk to him, because he was such a big person in my life. I think about him a lot, He's still trying to get me back, but I dont know if I can handle all of the drama anymore and trust him how I use to.

What do I do with the promise ring? I personally don't have it in my possession right now. It's getting resized, but I'll get it in about a week. I would feel really weird wearing it, because it still means I'm attached to him, but I also don't want it to sit in my jewelry box, because I don't want to forget our relationship and he put a lot of thought and money into it. It was the best year of my life and I made the strongest connection with him. I'll always love him, but that promise is shot to hell now. We're not going to be together even if both of us want it. Not right now at least. There's just too much drama. I miss him a lot. I miss how comfortable we were together. Oh well... Love hurts. Good things have to end eventually.
