mewsmuse - I agree that becoming a mother herself might have made your daughter realise what you felt for her.
I would accept any rapprochement from my daughter, even if she could not admit that she has been totally wrong. I know she is now in the grip of serious codeine addiction which has resulted in her having paranoid delusions about her sister and myself. She has now turned on her eldest daughter for 'betraying' her by keeping in touch with us. She is going to lose contact with her own two little grand-daughters but I know from all my research that addicts will put their need for their drug of choice before anything else, even their own family.
I am more upset by being cut off by the three children (all adults) who are still living with her, but I think they just can't cope with her manic ranting or they fear being thrown out - none of them has a job.
