So I know this girl who married a guy last August. Today, they're on the verge of a divorce. Why? Well...
She magically, out of nowhere, decided to get into anime/manga, began cosplaying, and ventured out of state to go to conventions - ALL behind her husband's back. Her con-adventures led her to cheating on her husband 3 times (like, cheat by way of sex stuff).
Her poor husband works his ass to the bone, and she goes around and meets and sexes with strangers from other states all while using his money... Yikes.
The moral of the story:
Yes, go find ways to express yourself and be creative and meet new buddies! But stay real and honest. Being creative doesn't mean you have to deceive the people closest to you.
Sigh.
