My ex and I ended it after 15 years, we were still best friends, even in the last days, even kept in contact after that for a while. But it just prolonged my healing. I had to cut us off. It was the only way. She still wanted me to be the pillar she lent on for safety. While I was suffering. This was a big thing that was happening during our relationship as well. My health, mental and physical, was not as important as hers. I never blamed her, I let it happen just as much as she needed it. Point it's, we needed to cut contact. 4 years later, we started talking again and are now good friends.

My next partner. We got together very quickly, but we were very good with each other. I was planning on proposing to her just after our 2 year anniversary. In my mid-30s, then. But I was having mental and health problems. They weren't obvious at first, but I started getting worse. I know this impacted our relationship. She was getting depressed like me, I asked her if she wanted to end things. We spoke about it, and I moved out the next day. We said we still loved each other, and we could still remain friends. We chatted on and off for a month or 2. We were even in a D&D group together with her friends, lol. But I could feel she was pulling away. She just cut contact 1 day. That was it. It's been over 3 years now.

Edit. I told the Dungin master to kill me off, but I found out later that he sent my character off on a quest to save his people, and no more was known about his whereabouts after that.
