We've spent 4 years trying to resolve whatever it is - basically since she had my grandson. That's what she says she is trying to do "sort things out" when she starts the communications. Mostly her ranting about me and her own family and friends, and my son (her ex) round and round in circles and repeating herself and me appeasing and sympathising and apologising. She often switches her target mid-discussion and suddenly it's her parents who are the villains instead, or my son, or some other friend of hers. She's fine when she actually visits, weirdly, but as soon as she gets home she starts again. I am pretty sure there must be something wrong with her, and so I have tried to be reassuring and patient and it usually calms her down short-term, but it always starts again. She texts faster than I can read and I don't know she does it! And sometimes she carries on all night even if I don't reply. Also she doesn't like me seeing my own daughter and I am scared to tell her if I am going to do so as it sets her off again, complaining I don't care about her as much as my own daughter. And she's started demanding expensive gifts and saying the children are not allowed gifts unless she gets them. (that is my grandson and his older sister). At some point during all this my son and I have lost contact - I think he resents that I tried to stay in contact with her and the children, but he won't tell anyone why so it's just a guess.
Anyway basically the problem I have is I do actually care about her - she's obviously very needy - but think it's affecting my own health now, as I feel as if I have been in brainwashing.
