What do u hate in people?

To be honest...i hate ghosting. When the person who u care and love just block u everywhere without reason. Thats happened with me not long time ago and I feel bad. Am I so stupid or bad to talk? Why is ppl constantly doing this with me, why? I can understand everybody and everything, but not this. If u wanna broke up — say it. If u have problems with partner online — tell everything. But please, not this shit.
