We love each other. We talk openly about everything and never fight. In that movie Jennifer's character fell in love with her friend who was a homosexual. They were the best of friends. In the end they both realized that sexual intimacy is not something that one can live without.
Intimacy is what distinguishes our friends from our lovers.
If you have reservations about this relationship, then I suggest holding off on marriage. As a child, I was brought up very strict. I was taught that pre-marital sex was wrong. I stuck to this rule. Being a male, I'm sure it's hard to believe.
