The feeling of support that grows between you, especially on your lover's part, helps you both to accomplish something big during the course of your relationship. You offer a lot of emotional support for your partner's ideas, and in return, they help you to understand the changes you go through as a human being throughout your connection with them. They're already attuned to making personal changes, so they aren't surprised by the transformations and incredible experiences you go through as a couple.
You are very affected by the whole experience, and you're very grateful for this person's influence in your life, even if it's a short-term one. A great activity for the two of you could involve learning and the expansion of the mind, so skip dinner and a movie in favor of a class in Zen Buddhism or whatever strikes your interest. Or at least make it ethnic food and a documentary film instead of burgers and a piece of comedy fluff, if you do go the dinner-and-a-movie route!
