<human>: Can you give me the gist of the text in a nutshell?

So, because I was a bit stupid during an argument that occurred during that awkward "let's be friends while I secretly try to win you back" stage, I have my ex-girlfriends's promise ring. I wanted it back so I could put it with the ring she gave me, because I'm sentimental and it hurt me that she broke those promises. After quite a few harsh words, (she wanted to keep her ring and I thought it was stupid for her to have an emotional attachment to it, since she dumped me) I got the ring the next day. Now, I realized she should be able to at least have that memory of the good times we had, and I also don't want it. We've been in no contant since Saturday, so I know I'm partially looking for an excuse to break, but I sincerely do want her to have it back. What's your advice? I'm not getting rid of it in any other way, so please, no suggestions of pawning it or selling it.
<bot>: I have my ex's promise ring from me to her, and I think she should at least have it for the memories. How can I get around NC and get it back to her?
