According to SSs, there is tension in their house, because BM is not getting along with her SS (her DH's son). He is 18 and just graduated from HS. He is working, but only 16 hours a week. He spends the rest of his time in his room playing video games. Apparently, he and BM fight all the time and her DH is squarely in the middle. I can't help but feel a little schadenfreude at BM's suffering. When she and her DH first moved in together (before she and my DH were divorced), she used to post about her "three" sons (my two SSs and her SS) and would post about how much she loved her SS.

Yesterday was six months to Christmas...how do I know? Because BM sent yet another message letting DH know that she felt it was "detrimental" to SSs if they couldn't spend Christmas Eve with her family. 

Continuing the MIL saga, after MIL invited herself to join DH on his weekend away with SSs, DH took a moment to tell MIL how hurt he was that MIL insisted upon meddling with BM and how he feels like he can't trust her. He told her that he feels like she always just makes excuses and doesn't take responsiblity or apologize. This is the second time DH has told MIL how hurt he was. Instead of apologizing, MIL just told DH that he was being unreasonable and people make mistakes and he needs to move on. So, he leaves it at that and he and I both talk about how MIL will not likely change.

I was familiar with the Betty Broderick case before I met BM, but become a bit fascinated by her after having to deal with the BM in my life who exhibits many borderline traits and in my view, could easily turn to a murderous rage if DH tried to challenge her on a) the children or b) money.
