If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
What does it mean for a person to be an end? In the example, is the end the continuity of the relationship, her happiness, or what?
If the end is the continuity of the relationship regardless of quality, or her happiness regardless of his, it doesn't look very "healthy". But if it's conditional on quality or on his own satisfaction, it doesn't look like the "end".
It means that this person's happiness/wellbeing is your terminal goal.
