Search Results: giving up on a loved one

In the book “all men and assholes and all women are crazy”, in one part the author talked about her last relationship and how it ended. She was seeing this playboy who was a little bit immature (they both were), who liked having an open relationship.

She became his favourite, almost definitively because she was the “craziest”, the one who was both the most dependant on him, yet also more importantly the one most willing to stand up to him. She still let him walk over her, but relatively speaking she was the most independent.

The two of them constantly going on and off, eventually decided to just call it off and remain friends. Yet one evening she was around his place, he told her he’s inviting one of his other girls round, so a sort of heads up, she can either stay or leave. This made her furiously jealous, and lost her shit on him.
She screamed into his face, presumably saying the most hurtful things she could think of (she’s a woman after all) for a while before she ran out of things to say, at which point she shoved him so he fell back, and he responded by giving her a hard slap.
After that the two of them just froze looking at each other, her with her hand on her red warm cheek. He told her to “get out, you psycho!”. She ran out, and called down a taxi. He chased after shouting telling her to stop, and apologising that he shouldn’t have done that, and she shouted back "get the fuck away from me!" as she got in the taxi and left. And that was the end of their story.

I think in that moment of her screaming the fuck out of him, and him slapping her for her pushing him over the edge, I’d imagine in his mind no other woman existed. And likewise, no other man existed in her mind either. I don’t think her objection was he hit her, I think her objection was he told her to get out; he rejected her, the only man that existed in the world.

Do you think I'm wrong? Would you rather be Slapped by the man you love, or Dumped by him?
