I am still fairly new to this and to solving major relationship issues. I have read your posts from the beginning and in place of some great worldly advice, which I am sure a vet will provide on here, I can only offer an opinion and support.
I am sorry you have gone through all of this but I admire your dedication and love for your children. I can relate even if our situations are different.
My gut reaction is that acknowledging the wedding anniversary means more to you than it does to her. Not sure why I would put it out there at this point. I understand why you are asking and struggling but I am not inclined to offer it up to her.
I wish you the best, will pray for you and your family and will continue to follow your journey.
