I think she said the ex had made false accusations of abuse against her DP Faery as part of the talk about child being poisoned by ex.
I thought she got a pretty fair hearing at the beginning, lots of people saying the problem was the ex turning the child against the father. Then responses became tougher as more details dripped out.
Then when she said it was ridiculous to think of having a room for the stepchild, even people who had been very supportive tapped out. I posted and hid the thread soon after that, so she might have gotten a hammering afterwards.
Maybe she wasn’t technically the OW, maybe that’s splitting it a bit fine for a 10 year old’s understanding, maybe the DP fudged some of his dates, maybe the OP did, maybe the Ex exaggerated to the child. I don’t know. All pretty plausible. All not the child’s fault and all likely to get the OP off to a bad start with the child, without the child being unreasonable in any way.
But definitely a murky position that wouldn’t exactly be starting on the best foot with the child.
And yes, for exactly that reason, don’t get involved with a guy who’s recently split up with someone.
A friend of mine started seeing a guy who had previously still be sleeping with/over at his ex-wife’s (well separated but not yet divorced from) house. In the full knowledge of the kids- Daddy stayed the night in Mummy’s room and he’s here for breakfast and to take you to school kind of thing.
She thought that was no issue “because to him it’s just an easy leg-over, it’s not an emotional thing”. But maybe it was an emotional thing to the ex-wife or his two little girls? Maybe the little girls thought that Mum and Dad were back together?
The kids gave her a pretty fair go as a new partner to be honest. They stayed over at his a couple of times a week and when she was there they were pretty nice to her/well behaved from what I saw and heard.
Then she started staying things like “Why can’t he just leave them behind and have more kids with me? They’re just getting in the way, I wish he didn’t have to see them anymore.” She list quite a few friends over that (including me). And to be fair to him, even though he was a total man whore sexually, he wouldn’t hear anything about not seeing his daughters and broke it off with her over it.
