Sorry to hear about the difficulties.
There can be many reasons why a person lies and why a person avoids conversation. It may be helpful to have a one to one non-judgemental conversation with the person he trusts to understand the situation/reasons including the consequences of his behaviour. If such attempts fail, he may need some professional help as he has long future ahead of him.
Best wishes
