Recently, my cousin came to me for advice. She had been in a three-month casual dating relationship and felt like it had the potential to become serious.

When I started asking her questions to gauge if she was ready, I realized that even though she had easily been on 20+ dates, talked on the phone for nearly 100 hours, and sent an endless number of text and Facebook messages to this guy, she knew NOTHING about what mattered for a long-term commitment.

When you decide to enter a serious relationship with someone, it is a very important decision. Therefore, I suggest it be well thought out. There are 20 things you should know before you get serious.
