The dream of a lifetime could be what one person in a relationship has wanted since they were a child, but it might not be what the other one has ever wanted. Moving far away from family and friends could be a career decision that will make one person's life better, but their spouse could find it an appalling situation. Supporting a partner is often more about events and feelings than it is about money. Giving a partner the love and approval they need when a decision comes along can make a relationship better in the long run.
Careers are very important in the modern world, and getting ahead is not always easy. If a person has been stuck at the same level in their company for years, an opportunity to move to a foreign location might be what they need to get it moving upward again. Their partner might have believed they would never be faced with this type of decision, yet there it is. If they want to support the person they love, honestly discussing and accepting a transfer might be best for both of them.
There are times when a person sees opportunity with less pay as a better way of life, yet the person they are with could see it as a demotion. Living a dream is about personal feelings in many matters, and not all people see income as a measure of success. The family might have to cut back or make sacrifices for one person to have a particular opportunity, but giving them this chance could be what makes their relationship solid.
There are many ways of being supportive of a partner in good times and even bad times, and some of them require sacrifice. Loving another person and building a life together is not always a smooth road, but the bumps can make the relationship even better.
