I have met Several women (And men) like this in my Lifetime. So shallow as to Blow off a potentially excellent Partner because they were of Unacceptable social standing (ME!, Date a Laborer?? NEVER!!) Or they don't look like a Movie Star. "Marta"s behavior is never likely to Change. She will continue being selfish and socially Inept, and she will continue to Blame others for her Lonliness when the Only one to Blame is Facing her as she brushes her teeth in the Morning.
Some people are Lonely for a Very good reason, and from now on, before you set her up again, Ask yourself how good a friend you are being to any Man you are sending in her direction. I think they Really wouldn't thank you for the experience.
