several different sources say that the percentage of high school relationships going into marriage is from 8% to 11% and 5% don't get divorced. yeah so 5% of high school relationships actually work out. but depending on how close and passionate you are with you're potential significant other can alter that. i also saw that if your best friend in high school is of the opposite sex and you get married to them that the chance of staying together goes up to about 38% and if you have a christian based religion, it goes to 42% and of them (with Christian based marriages) only 3% are divorced.
