I was 15 the first time I thought I was "in love". I was so wrong!
We were just out to dinner last night with an elder who just turned 30, and he says brothers and sisters keep asking him when he'll get married. He said his most important qualification for a lady is love of Jehovah translated into reasonableness. And I don't want to be a traitor to my gender or anything, but not all women have developed that fully before they're like 25 or 30 because we're just more emotional. Take your time!
