That's her take. Maybe she's right and that's how it went down.

Or maybe, by the time the partner left, they were done trying to compromise, talk, reach the OP.

The reality is that some people are just self absorbed. They think if they're happy then things are good for everyone. They won't hear any different no matter how hard you try.

We haven't heard the abandoning partners side. We don't know the OP well enough to rightly determine their version of events is true or not.

It might be. But we don't have enough information to know that with any real certainty.
