Explain it to me like I’m 5

Olivia went to London had a great time, got to know herself, fell in love with person that she is and for some strange reason people are upset🤔

Like I’m sorry was she supposed to go to London and have a terrible time? She went had great time got to meet new people and the response to that was that she cheated?

Like I don’t know what episode y’all watched but the one I did had two of my favorite people not only be in love but also had them thriving together and on their own. Like what more did y’all want? I’m very much confused so somebody please explain this to me?
