I mean, there are two issues:
One is, almost every piece of furniture, certainly every picture on the wall, etc, etc, I chose, I bought. But then again, he mostly funded it, after derailing my career.
There's also the issue that our younger DS (20) has ASD and MLD and would be lost without familiar things. Then too, because of DS (20) situation, I would want his father's house, when he visits (only in daytime if I can possibly help it) should look friendly and familiar too.
But, you know, I'm not feeling that friendly towards STBX right now. And I will do my level best, for safety reasons, to make sure DS2 (we have other DC but DS2 is especially vulnerable) will never again be near him overnight, or for too long. It is because I cannot trust STBX that I am belatedly, very belatedly, seeking divorce. The older DC are neurotypical and I wouldn't interfere.
I am happy to let the lawyers sort out the actual money.
I am unreasonable to say: the rugs, the pictures, all the furniture I chose are mine, whoever was actually earning the money.
I am reasonable to say: keep your money, I will keep a familiar cave for my children.
