Nobody should have to abandon their success for the sake of their relationship.
We are all familiar with the classic Hallmark movie narrative: the high-flying businesswoman gets wooed by a lumberjack and quits her city job for romantic bliss in her rural hometown. In reality, though, not every woman is willing to abandon her career for the sake of love. There is nothing wrong with moving for a partner if it is what you want and you have a safety net in place, but it is still a risk in even the most stable of relationships. For every happily ever after, there is a messy breakup in a place that you are a stranger to.
The unfortunate truth is that any big move for the sake of one partner usually leaves the other losing out in some way. Relationships should be collaborative, and this needs to be fully taken into consideration before anyone even thinks about making such a decision. Professional concerns are one of the most common reasons why somebody might be hesitant to up sticks, but not everybody takes it seriously when the person they love is worried about their career. They can only see what they want for themselves.
