MYTH: If a man isn't interested in talking marriage with his long-time girlfriend, he's immature. LW1 revealed HER immaturity at several points along her letter. This includes making reference to the fact that in her "small southern town," many women are married at her age and have kids. So then, a sign of mature thinking is justifying your actions because most people in your little small town do it? Her boyfriend is wise to hold off. Gee, it's not as though at age 20, one's bio clock is ticking.
