One of my movie screenings last week included the new Ashton Kutcher/Natalie Portman feature called 'No Strings Attached.' (The movie is releasing in South Africa on Friday, 1 April).
I have been in a similar situation as the main characters of the movie. You meet someone and feel physically attracted. Sexually you enjoy each other's company, but refuse to start a relationship.
However, being physically involved with someone creates a shared 'energy' if you like, and falling in love is really unavoidable.
I find it fascinating to hear that some people actually do maintain a 'no-strings-attached' relationship. Perhaps one of the two people in such a 'bond' just ignores the real sensation of loving someone, and chooses not to have a fully fletched relationship. Whether you believe it is truly possible, or not, it's really hard to be sexually involved with someone without feeling 'more.'
In this movie it becomes clear that falling in love is inevitable. One of the messages though is not to change who you are. That being said, it is important to accept someone else for who they are. I think this is almost the most important aspect in a relationship. If you feel comfortable with yourself, you'll also be happy with the person you're with.
