Chances are the love of your life will be attracted to someone else at some point even if they are blissfully happy with you. That is human nature. It is normal, even healthy, to have physical attraction to others even when you are solidly in a committed relationship.
The sooner you accept this fact, the better. Can you honestly say you have never been in a relationship and been attracted to someone outside your relationship? If so, I think you are ignoring those feelings.
Physical attraction is normal. It is even primal and natural. Some say our DNA determines who we find attraction, who would make the best DNA match with us to produce the strongest offspring.
