What you do together is life. What you think about doing together is imagination. Bringing those to ideas together into all the things you like to do, anticipate doing in the near future, and aspire to do as part of your long-term goals... All of this is part of building and nurturing a relationship for the future.
The final part of finding the love of your life, is to let go of all other relationships. Do not compromise in your love life. Any little miss in your present moment will become a roadblock in the future.
