So me and my girlfriend broke up, she basically said she wanted to focus on her self and be friends and I decided to go to no contact and not be friends. We are in this group chat with each other with a bunch of other friends on whatsapp, and she is constantly being hostile towards me or trying to make me jelly by flirting with other guys. Should I leave this chat? Or will staying silent and letting her know that I am reading this shit and not giving a fuck work better?
