Things ended quite badly. I reached out a few times, offering an olive branch - no response. I wasn't the person that caused the break up or the fights (partner 'split' on me and never seemed to calm down, then they simply stopped responding to me after saying we could be friends) yet I still did this. I also still feel sad that things ended this way, and everything feels really unfinished. I've considered reaching out again, but I already did that and I didn't get anything back. It seems that this person is happy to leave things like this, whereas I am really struggling with it.

What should I do?
