I am thinking of casually inviting my ex to a public botanical garden to be a model for my photography. But I want to make her jealous by also inviting her good friend. Should i tell her i am inviting her friend? Should i tell her friend i am inviting my ex? Should i pick up her friend first and show up with her at my ex's house? Should i invite another of her friends so it's not that obvious? Admission to the park is $25 and i was thinking of paying for both of them. Should I? Is any part of this a good idea?
