I Don't Feel That The Chemistry Is There

When do you feel "The Chemistry" for someone? Is it when you first see a picture of them? Is it when you get an email from them? Is it when you first meet them in person? I'm curious. One of the reasons for closing a potential match on an internet dating site is just that. "I don't feel that the chemistry is there." A lot is based on whether one likes the picture presented. If you pass that test, there are others. Finally, you start open communication. What should you email about? What is it that people are looking for during the email communication period? What are the magic words which help you pass that part of the test? If you pass that part of the test it's suggested that you communicate via the telephone a few times before you decide to meet in person. I guess meeting in person is the ultimate test if you get that far. What is it people are looking for? Are people too fussy? Or do they just give up too soon? Or are they just trying to amuse themselves? I've been introduced to many men on the internet dating site. Some I've actually communicated with. It's been almost a whole year. I've "closed" some matches and have had some "closed" by someone else. I'm beginning to wonder if this is an artifial way of meeting someone and a waste of time and money?
