How can I stop her from finding me?

Anonymous
So little bit of context,

I dumped my narcissistic ex over 8 months ago but she’s still harassing me the police won’t do anything so I’m having to live with it which isn’t helping me at all.

Well I wanted to go on my PS4 and play Red dead redemption as I liked playing that game, well I know if I go online and play I’ll obviously get her harassing me on there, so my question to you is, is there a way I can block her without her being able to harass me? I know I can block her from messaging and seeing my profile but can I block her from seeing me in the game?

Don’t answer if you are not going to tell me how to block her from playing with me all the answers you’ve given are useless. 🙄
