That towel my darling, is one heck of a towel to throw. While many would have come close, only few manage to. Somehow we prefer zoning out emotionally and carry on. My mum has a opposite balcony where a working women lives. She comes home everyday to a pile full of dishes to be washed and a pile full of dirty clothes. She starts cleaning them at 11:30pm and she rants as long she does it, about her husband being indifferent, that she needs to do everything and no one ever cares. About property and everything else. She goes quiet by 1 am or so.I visit my mum every other year and I hear her every time I go, year after year after year. I don't know the whole story but I wish she finds some peace someday. To answer your question: Personally it should either be major blows intentionally to my self respect or repeated emotional/ physical/ financial abuse of my children. Once those few chances are exhausted, I leave. Simples. For you?.. only you know. But when you do, be brave.
