You don't get shamed directly, it's always an implied thing. You'll almost never get a girl shouting at you in public to leave her alone, it's usually "shown" to you by ignoring you/your calls and then a week later flaunting a new boyfriend in a place she knows you will see her with him. Girls never verbally shame guys, they emotionally shame guys by "sending you a message".

But, that being said, giving up is out of the question. I know that one day somewhere, some girl will not do this. As I said before, even if you have to date 1,000,000 people, somewhere it will all work out in the end!
