Good for you for sticking to your moral compass and not allowing that which goes against your integrity to get in your way any longer.

You have every right to cut her off. If she feels judged that’s on her con science not yours.

Hold your head high. You’ve done nothing wrong and in fact you’ve done everything right. You don’t need to entertain her any longer. She’s making these online friends because it’s very likely in real life she’s rejected by people because of what she does. So in actual fact I think she was just using you like a puppet and you’ve stood your ground.
