It absolutely "can" be but that's wholly separate from making an declarative statement about what reality "is" for people who chose to terminate their romantic relationships or why.

And sorry if you feel that was a "personal attack" because I posited that such an arbitrary and unsubstantiated declaration about the reality of relationships might be coming from a mindset that doesn't give attention to the nuances and idiosyncrasies of relationships or the decisions individuals make in them.
