Meggem, stay very level headed about money or you will regret it. As soon as he forms another relationship and moves on and someone else is getting the benefit of your generosity, you'll see what I mean.
This happened to me, and not in a bitter divorce, but suddenly I realised he was getting on with his life, and anything I 'gifted' him out of misplaced kindness would contribute to a life I had no part of.
