How many people cut people off when brexit happened ao many threads on here about how they couldn't believe their feiend, family members thought a certin way they didnt agree with and therefore didnt want people who shared those views in their lives.
These were people they had known for a long time.
You can know someone sure be close with then and then they go and do something and it can chnage how you then feel about them and whether you want to continue a relationship with them.
Taylor Swift cuts ppl off the moment that person is in the press for something negative she distances herself and cuts them off to protect her image no doubt cant be associated with them anymore well at least not publicly.
Eugene has just cut herself off from Andrew...why..that is her Dad after all and why now...protecting her image doesnt want to be associated it with all the awful stuff coming out about him.
You might know someone for many yrs be close with them but you can never truly know them just the version you get.
