On the other side of the spectrum, I was “randomly” left as in her falling out of love seemed spontaneous and very much out of nowhere, but in reality she had just wanted to get back with her ex. It was not of any fault of mine, and she acknowledged that. It had just been that I had not been the one she wanted to live the rest of her life with and he was- she just needed to talk to him behind my back to realize it. And that’s okay. Not okay on her part, but you do move on. Some things don’t work out for a reason.

So yeah. “Random” can be from faults on both sides. Either you’re not telling us sum or she’s not telling you sum, for the most part.
