I can relate to your second karmic experience. Mine went on for about 2.5 years and it was intense. The back and forth pushed me to some dark places. I was in my mid-30s and started doing things I’d never done before just to cope. There were times I honestly didn’t know if I’d get through it.
The way we treated each other still bothers me when I think about it. My friends basically sat me down and told me I needed to snap out of it. They’d watched me lose myself in this relationship, and they were worried. I was pissed at them at the time, but looking back, they were right to do it.
I’d lost a ton of weight and didn’t even recognize myself anymore. I’m in therapy now working on codependency stuff. My other relationships were pretty easy, so I never had to deal with any of this before. This one kind of forced the issue. I can’t see myself ever talking to this person again after everything that happened between us. We were just toxic together.
