I'm going to ignore and hate a girl who left me on read multiple times and have genuine hate for her
so why do you want to hate her?
When she ignores me it makes me feel like shit, also if she wanted to be with me, why isn't she talking to me
Your anger is totally justifiable. It's wrong on their part to not to respond you. Maybe she's busy with something else?
I think she is just ignoring my messages.
As long as you don't escalate things, it is fine. You don't have to like her but you can just move on too.
