Just wanted to drop in and say good job man. I think what you did going above and beyond out of thoughtfulness for your wife's desires will yield you benefits down the road. I know her response must've made your day. Your taking the high road will give you peace regardless of the outcome of your sitch. You are fortunate that you are in communication with you W, I wish I had that opportunity.
I've tried a similar approach with my W, not doing something directly for her but in investing in 529k's I set up for my 3 stepkids. I have no expectations in doing this and will continue at least to the point if/when she files. I haven't got a thank you, but when I look back on this in the future I can honestly tell myself I left it all on the floor, as you are doing. 8 months in and I think I am finally adhering to the DB principles (as long as this act isn't pursuing behavior which I don't think it is, since the benefit is direct to my stepkids not to her).
Good job and good luck, don't be lonely on the high road I am trying to be right there with you. :-)
