From what you wrote here, and forgive me for not remembering the gist of your other threads, it sounds like Darling "moved you in" with him and his wife without really consulting her, even though she lives there with her children. Maybe not everyone here is on board with the idea, and there you are making yourself right at home, while she had no say in the matter. I may have understood it incorrectly - did all of you sit down and talk about it beforehand, planning things carefully, or did your bf just decide for everyone else what was going to happen?
