First post Internet relationships

I am writing a novel set around internet friendships and have done much research into emotional relationships. I have not been researching the internet dating scene, those people who are actively  searching. Instead I have. been looking at relationships that have occurred serendipitously. Relationships that spring from chance meetings on games sites or the social media.Many of these friendships and subsequent emotional bonds happen to people already in partnerships or marriages,some strong, some rocky. I want to explore some of the issues around this area . I want to explore the issues of ethics, of how to guard your heart in a fantasy world,maybe the rules one needs to think about. To get those of you in such a relationship or about to embark on one to think about the ramifications. I hope to share the views of real people with the views of some of my characters. So this is my starting point, hope its an interesting journey.
