I am peeved and confused! The 'other'woman had children by my former beloved husband while we were still married. What's done is done, right?

Well, those children are my children's siblings. My children are 21 and 18, no longer eligible to recieve benefits that exceed $1000 per month. My daughter will for a total of 4 months, a third of the thousand. His insurance money will be coming soon to which my former left solely to my his eldest child, my son.

Now, my problem is this; do I tell him to be fair and split it evenly amongst the 4 of them, despite the fact that $1000 will be added to their household income? Or do I just have him split it amongst his sister, my daughter?

BTW, the $1000 per month is not being dispersed yet because this woman has the burden of proof that her children are indeed my husband's children. Till then, Social Security has all monies on hold (i think they gave her 90 days).

What to do?
