When people look online for love they look for a relationship. First you start talking to someone and then if you like someone you eventually meet. What if the person you are speaking to says you will meet but never does?
If someone spoke to you for over a month and still haven't met something is up. There is nothing wrong with taking things slow but there comes a time when it comes to being led on.
Weather it is you or someone is doing it to you it is wrong. If someone is not your type or you just want to be friends then you or the other person should mention it right away. The longer you stall it the more you are leading someone on.
It is better to be honest right away then to continue something that is not there. Later on someone will get hurt. At least if they know right away they could look for someone else instead of waiting and wondering. Love is out there for everyone. It just takes time to find the one for everyone. There is a saying you have to kiss a lot of frogs to get a prince.
