The best thing an active ADDICT can do for you is leave you alone. My most recent ex also sends me roses whenever he is guilty. The other day I saw he liked Playboy in Facebook.
I can be perfectly happy without any flowers. I can buy flowers for myself. Flowers are NOT a replacement for basic respect, dignity, education, sprituality, recovery and all I put on the table and deserve from the partner.
Hope you get rid of the flowers anyway and perhaps give someone else a smile. Also, do what suki says
