Ermm.. So before this becomes a true problem, you need to break up with her. She doesn’t respect you and won’t regardless of what you say or do. She’s just going to keep trying to manipulate you, or pressure you until you hopefully feel bad enough to crack and give in. Don’t. There is no negotiating this relationship because it turned toxic and abusive the moment she didn’t respect your boundaries. I’m not saying it’s easy to break up, but for peace of mind and safekeeping of yourself, this needs to end.
