A is with B, but living on money from Z. B himself supports C, who lives with her child by V. V wants to move to Seattle but his child lives with C in Ephrata. C cannot move because she is having a relationship with U, whose child also lives in Ephrata, though with its mother, T. T takes money from U, C takes money from B for herself and from V for their child, and A takes money from Z. A and B have no children together, thank God. V sees his child rarely but provides for it. U lives with C's child but does not provide for it.
