One piece of advice. If she does not make a full recovery from the brain injury and if she will need long term supports and disability that needs some specific thought in terms of how to handle the divorce. $4000 a month may not be in her best intersest if she has a permanant disability. It will exclude her from getting SSI or SSDI. There are protected trust funds that can be establishd for people with disabilities but the lawyers need to know about them and know how to advocate for people with disabilities. This is what I mean when I say that you don't have to take care of her personally to make sure she is taken care of.
