Here's something to tell a man when you are tired of explaining why things won't work out - "be honest with yourself, if I were to invite you for dinner and introduce you to my family, do you think they would be pleased and I would be proud?". Save yourself the time to explain things, let him self reflect. If he doesn't pass this test, he is too low value to date women in general.

It's incredible how seemingly little common sense men have. Some of them walk around without a job, in debt, balding and overweight and look like they don't shower and still have high standards.
