Mae Mary* wedi byw drwy gam-drin domestig; roedd ei chydweithwyr wedi sylwi bod ei hymddygiad wedi newid ac eisteddodd un ohonynt i lawr gyda hi a dweud ""Mae hwnna'n un clais yn ormod". Roedd gan gymdogion Mary eu hamheuon, ac fe wnaethon nhw weithredu pan aeth ei merch atynt am help.
Mary* is a survivor of domestic abuse; her colleagues had noticed her behaviour change and one sat her down to say “that’s one bruise too many”. Mary’s neighbours had suspicions and became involved when her daughter went to them for help.
