I am confused too. I can't help but think there is a reasonable explanation for this. A tragedy in his life, a death in his family, a destroyed cell phone. I would hope that there is a explanation and he will contact you with a great story. Otherwise you won't know what the problem is. I feel sorry that he hasn't been more honest. At some point you have to assume that he has written you off. But that doesn't make sense so just have faith for right now. If it seems that he is that rude to go weeks or months you have to accept that you won't know why and move on. I would abandon the communication at some point because it hasn't helped the situation.
Please press accept; this is the only way I am compensated
