Girlfriends and boyfriends are for high schoolers and first years in campus. But when you mature, you need mature love, someone to build love with a purpose, with the intention of marriage, something lasting not some excitement just to pass time.
When a gentleman matures, he longs for a grown woman because a girl cannot handle the depth of love. When a lady matures, she longs for a grown gentleman because a boy is just not ready to handle a grown woman.
