To me my employer is my customer. We don't require each other's allegiance, just an ongoing mutually beneficial transaction and good will. When either fails for either party it's time to move along. Devotion isn't part of the arrangement.

Similarly:

I got badly burnt in a relationship once.

After that I promised myself not to get hurt again. If you don't love each other any more, accept that, and walk away.

Worked for me, and I stayed friends with almost all my ex-es after that.
