Here are a few caution signs you should watch for when dating online.
1. No definitive answers.
You ask how old they are and they respond with something like, "it doesn't matter".
2. Following up and reliability.
Doing what they say they were going to do and responds when they say they are going to respond.
3. Consistency in writing style.
4. Doesn't want to exchange pictures.
5. Only emails late at night and in a cryptic style that is hard to understand.
6. Immediately wants to meet or says I love you after just a few messages.
An overall good idea in online dating is to follow your instinct.
