I to be devils advocate …. Dating is not a partnership. You are literally just trying to find out if your compatible with someone and if your not then you move on . In that context , she did nothing wrong . As far as having sex with all these folks you are dating , that could be a diff convo.She’s basically saying she’s selfish.
She doesn’t know the concept of being in a partnership. She likes the idea of a relationship and the comforts/perks that comes with it. But she doesn’t want to work and/or sacrifice to ensure a long lasting/healthy survival
When she said that the situation is “no longer serving me” , thats selfish . To me, that implies it’s all about you .
