I have posted here before about my very difficult relationship with my husband and the realisation I need to leave him but we have just found out his mum has an aggressive form of breast cancer and now I don't know what to do. I know he is really going to really struggle with this as he is very close with him mum. I want on one hand support him but the other I know its not nice to say as it is him mum but I know this is going to lead him on a downward spiral that I don't think I can cope with.
