If you don’t have marriage line, it means that you have no desire to love. You are not interested in or couldn’t be attracted by the opposite sex. You usually don't pay much attention on marriage and may be sexless. Instead, you like to focus more on your hobbies or career. If you already married and don’t have the marriage line, the most case is that you don't have interest in your partner. Just for your reference.
