Nobody knows her intentions but her. At this point everyone is an adult and should know how to communicate what they want. Are you leaving the decision to be together or be apart solely up to her? If so, why? What she is doing is manipulative and emotionally abusive

I wouldn’t hold my breath about it OP. Seems like she is just stringing you along. Set clear cut boundaries w her or you are going to end up hurting yourself holding on to hope. If she can’t be straightforward then you decide for yourself
