i too would delete her i had to do with my daughters alcoholic mum as she was having a go at me cos her son preferred spending time with us and not her for obvious reasons given there was constant arguments there. I dont know if and when she found out i did this but well i dont have to deal with her face to face so i can see how its more diffucult for u to do and i too worry what ppl think of me doing certain things but for me i was fed up been her battering ram cos of her guilt over her son.
What i dont get is how i have no issues with getting rid of her and other A in my life but the exA has been another matter was so much harder been rid of him and still is keeping him out.
Id maybe have a quiet word with her and see if it calms down if not your justifed in deleting her as for your daughter i would get her to delete her she has no need to have her on there really and as someone else said just say ohh did she do that must of been a mistake and dont add her back on xxxx
