A mess ...
Let me see: You have:

class A
{
 ... reference to class B ...
};

class B
{
....reference to class A ...
};

problem? (the chiken and the egg ;-)
If that's your problem use 

class B;
class A
{
 ... reference to class B ...
};

In the header where class A is declared and:

class A;
class B
{
....reference to class A ...
};

In the header where class B is declared.
