This isn't a mono perspective, this is a human perspective. Each one of us has a criteria to invest in others. That criteria governs our actions and also determines what the actions of others are to be if we are to invest in them. This is not about one sided control of a partner or trying to fit a square peg into a round hole...it's people who have the same shape coming together to fit.
Sometimes these criteria change - mono to poly/ poly to mono for instance. At these pints everyone should consider if the relationship can be sustained in a healthy fulfilling manner. If not...then it is time to move on and perhaps seek someone to invest in who does meet our ctiteria.
