married to the family, i think i'm married to the whole block
sounds to me she's embarrassed about asking you to help her kids out til they have left unias you have not offered to help, or have you ??
so what do you want to happen to her kids (thou not really kids being 23, 19 and nearly 18) ?
maybe she wants them with her or you to help support the 2 younger ones ?
thou uni costs are not much compared to here.
