If I were in your shoes, I think I would agree with Gucci and City Girl and go NC.
I'm still suprised that you sent 3 sets of flowers.
Just to give you an idea of where I was coming from, I think I have given my W three gifts TOTAL since we've been separated, and she did not respond negatively to any of them. They were each small gifts and were several weeks apart each time. One gift was kind of a "gag" gift. She opened it and started smiling. That's the kind of effect you need a gift to have.
I have also given each gift in person and I don't think you have the opportunity to do that right now.
