Gossip time

I had a good time with my friends, except for the fact that I argued a bit with one of them because I disagreed with the choice she made regarding her boyfriend. I don't know if I'm right, but she made a big sacrifice for her current boyfriend, who cheated on her just two weeks after she made that sacrifice. I told her that he doesn't love her but sees her as a trophy, and since he is convinced that she will do anything, he feels he can prove that he doesn't love her. She got upset and wanted to leave, but I calmed her down by saying that nothing I was telling her mattered. She still insisted that he loved her, even though the facts were right in front of her. In reality, I saw that she was quite upset with me, but I couldn't lie to her. She is really good, continuing to treat well a person who cheated on her. I imagined what I would have done in her place, and even if I hadn't done anything, one thing is certain: I wouldn't want to see such a person again. I don't understand why such good people deserve to stay with monsters.
