relationships

In Australia 75% of marriages end in divorce, thats not a very e ancouraging statistic, why is this so? Most relationships are based upon physical attraction, religious views and ideologies,peer group pressure,safety and stability etc ; all noble causes but it doesnt have to be the norm.I myself have been celibate for 20years,meditate, am a vegetarian and have very wholesome relationships with a whole range of people.I live in a community and my main relationship through meditation is with God, not in a religious sense but a practical,feeling relationship and thus all other people relationships are smooth and accurate
