Judge and court will determine duration and amount of spousal support if she asks for it. From a moral stand point I believe that grown adults should support themselves and not rely on others. It’s ok to help others to stand on their own two feet. It’s not ok for one adult be fully dependent on the other, ex spouse or not. It’s so unnecessary

Having said that, it’s perfectly fine to help her to get on her feet BUT be mindful of danger of enabling her. Sadly it happens too often. She keeps relying on a man while married and then continues this life style divorced.

But what happens in the future? Will she rely on you for the rest of her life? Or is she planning on becoming self sufficient? If a woman chooses to stay home when kids are all grown, then she also needs to understand that she’ll have nothing to rely on if her spouse dies or divorce happens. It’s not particularly wise choice. Too many women find themselves destitute because they chose to stay home (beyond young child care years when kids aren’t attending school yet) for many years and choose to rely on alimony after divorce. Eventually they find themselves relying on welfare and charity of others because they never learn independence . Sad way to live

I’d encourage your wife to become self sufficient and try to help her perhaps learn ways of how to become independent. I’d not encourage her to be dependent on you for longer than judge decides. It will do her no good. It might look like a kind gesture on surface but in a long run making others dependent on you is a questionable thing.
