So either you are doing one of those. Let her feel the full wrath of responsibility ( children, bills , taking care of home, work ... etc ) while you step out for a few weeks breather

Flowers always make people better, happier, and more helpful; they are sunshine, food and medicine for the soul. unconditional love is awesome!
