Just far fetched speculation, the CTC benefits were being paid but the money was going somewhere else. IIRC it her grandmother who she told this story to. I could be wrong. Regardless it was the same person who repeated that she had said DM wasn’t treating her well, so rightly or wrongly, so why not pile the blame on him for the money issues? Just because it’s apparently true her ex quit paying child support doesn’t prove DM wasn’t filing his tax and they weren’t getting CTC, which IIRC worked out to $1900 per month.
I’ve always felt there’s much more to MBM than her racing away in silence to this very day, although I don’t believe she harmed her children.
But what would cause a financial drain? Blackmail, drug addiction, online gambling addiction, helping out someone else in greater dire need? Could be anything.
