Dear Prudence,
My ex got another woman pregnant while I was pregnant with our twins. I didn’t have any money, nor any family to turn to. So I grinned and accepted his apology until I could start work again and secretly save up money. He died when our twins were five. His death benefits were between all three kids but the life insurance was enough for me to escape and start a new life. This left bad blood between my mother-in-law and me. She accused me of stealing her grandchildren from her and being greedy. It led to estrangement where I would let the twins talk to her but not visit because she made threats of taking me to court over custody.
At that point, their half-sibling was not connected with us. My twins knew they existed but only have hazy memories of meeting them. I didn’t know that their grandmother had taken custody of the other child, as the mom is in jail. And now, their grandmother is dying. I had a caseworker call me to see if I could take temporary custody. I froze and said that wasn’t possible. Now I don’t know what to do. I don’t know how to explain this to my twins. I don’t know where to start. Intellectually, I know that it would be a disaster to even think of getting involved in this mess, but the idea of this child in foster care gives me nightmares. What should I do?
