I honestly don't know why he would be doing this. I have a girlfriend that does the same thing. She continues to meet men on the net and so far all of them have only been after one thing. I know there are some success stories out there but when you are a nice looking and genuine person there must be a reason why you feel you have to do this. Maybe deep down he has some sort of social problem. My friend uses the excuss that she is shy and lonely and that it is easier to talk to someone not face to face.
