that's a very good question, and im happy to answer it.
the thing is, when we're young, it's easy to fall in love. but usually (and im not saying for all), young love doesn't last forever. heartbreaks, betrayal, and bad things come along with something great even though we don't like to admit it.
but the thing u start to understand when ur growing up is u start to see more things in people that help u make better decisions and therefore, being wiser when jumping into a relationship. in other words, we've all been through it. there's no such thing as "deserve" love. don't get me wrong, love is good and nice to have in our lives. but things happen for a reason. and just because u don't find love now, u shouldn't feel down and envy anyone else. u move at your own pace. people's tastes change. so don't worry or try so hard to find love. it'll find u on it's own. the people that NEED love, r making a mistake. because the greatest thing u can ever do in a relationship is realize that your love for each other is greater than your need for each other. i know this all sounds corny, but it's mostly true >.< i have lots of sources.
