i've had similar experiences so I can definitely appreciate what you are saying. Its all about keeping up appearances and its how woman show domination over others, going to fancy places and you spending money they don't have on overpriced places so they can capture every magical inch on it for Instagram and have people fawn over the lifestyle they live
Like you said there are plenty of guys willing to play the sucker and treat her to what she wants so its no loss to you or her, just a mismatch in ideals and priorities
As I was reading through the post I was waiting for you to mention her saying she needed money. From my experience with girls of this nature if you're around them long enough it always comes down to something where they need money but it's not the borrowing kind more the give me kind with no obligations.
Glad you saw through it and came out of it a richer man lol
