Most of that is correct except the part about her new husband John. She kicked him out because HE is the one who told me that Sheri had gone visiting and being social with her friends.
He told us. She then dumped him.
I'm replying to my own comment to further clarify that John and Sheri were having issues before this. Sheri told me a few times they were "in a rough patch" to use her words. Him telling us where Sheri was is just the straw that broke the camel's back. Issues had been building between them from before they got married. I mean, the speed at which things progressed between them is mind boggling. Met, dated, married, and divorced....all in 5 months.
Thanksgiving 2019 to now.
John was very frank with me about how unhealthy this relationship became for him. He told me on the surface they were completely compatible (and they were, the first thing I noticed....they had identical interests, strengths, sense of humor, same tastes in stuff, so many similarities) and he fell so completely in love and was so excited to have a fun life partner that he just didn't take the time he should have taken to get to know her better. Superficially they were 100% alike, and he is angry at himself that he didn't dig deeper.
He sent me a long text in which he explained he tried for 3 months to buy a house for them and she wouldnāt be satisfied. She undermined him and complained of every location and made it impossible. I'm mentioning this because Sheri complained all the time about how John was making her (Sheri) do all the work of finding a place. She didn't mention that was because he got sick and tired of presenting dozens of places to her and her turning them all down, so he finally just told her to find what she wanted. I went looking at several houses with her. I was surprised that she was looking outside of her price range. She told me more than once "John can afford it."
She also expected to still work and make money (before the quarantine) but insisted John pay all her bills. I was in the room during several arguments where Sheri was demanding John pay for something (in one case it was a medical bill of one of her kids, in another her credit card payment) and he was pointing out that they were expenses incurred before they were ever together, and though he was willing to split expenses in general he wasn't willing to just take on all her debt. She was really angry.
She complained that John was hard on the boys. I never once saw him deal with them any differently than Sheri herself did. He modeled his interaction with the kids on Sheri's own. I heard her countless times threaten the boys with John as a way to get them to mind...."You better act right or I'm gonna tell John/John's gonna deal with you" etc. wilding him like a sword or hammer. And then she turns around and says he's too hard on them?
I think what really got to Sheri was that he finally called a halt to them buying a house. I witnessed that conversation too. He said now wasn't the right time, and she completely flew off the handle. My opinion is that once she realized that he was not as invested in her and their relationship as he had been, and was taking a breather to sort things out, that's what tipped her over the edge. She couldn't use him and his money? He wouldn't buy her the home she wanted? He wouldn't pay for stuf? She was done with him. On to greener pastures.
All of the relationships she had prior to John that I know about/knew the men, they all ended because of money, though in every case Sheri insisted it was because they were mean to her and/or the boys, etc. I had conversations with those men just the way I have had with John, and in each case Sheri was furious about some kind of money aspect. The first one wouldn't spend any money on her. The second was way to frivolous with his money and wouldn't listen to her about how it should be spent. The third changed jobs in order to vastly increase the benefits to Sheri and the boys and provide a much better financial future for them over the long haul, but because it made $1 less an hour she was done with him.
And then there was John. Who wouldn't by her a house.
So she basically betrayed him also.
