I would be surprised if your T was purposely making you repeat yourself, that sounds cruel. I would prod more to find out if she forgot by reminding her you spoke on your last session about your feelings about her and it was difficult. Even ask her outright if she remembers what you talked about. Sometimes when a long stretch has gone betwen appointments therapists need to be reminded about what you covered. She sounds disorganized as I think this is something she'd write in her notes. The late texts regarding scheduling is not that weird if she uses texting frequently for this type of thing. If something comes up last minute she might text you right away so she doesn't forget.
