In response to the op, i would just go with your instincts - i don't really buy the whole busy thing. Most people have internet on their phones now it takes 2 minutes to respond to a message - how busy do you have to be? There are of course genuine reasons why people don't reply but if they were serious about the whole process, they should at least try and get back to you about why they can't be in touch at the moment. I'm not really sure dating sites work to be honest, the expectations are often too high and you can come across as desperate without this even being the case. Do you think maybe you're more interested in the idea of a romance? People can become obsessed with experiencing something they've never had before. If you can, spend more time going out into the real world and try to meet people through activities that YOU enjoy. Maybe then you'll get a better idea if it's something you really want in reality. Just my thoughts. Good luck.
