I think it’s very common to want or get a pic with a gift so don’t think you’re out of line. As a woman I’d say you got played. She’s either got a bf or husband but probably has a few guys sending her gifts. She probably doesn’t have the shoes anymore. Probably sold them. That’s why she is so adamant about not sending the pic. She’s gaslighting and manipulating you. Be glad you found out before you got in deeper. I’m sorry you got mistreated and ripped off.
