I really need some help and advice, Im sure my wife is bipolar or schizophrenic, she has real issues with her 12 year daughter/my step daughter, her moods change quickly to getting nasty to the both of us, but more to my step daughter even to the point where she told her obviously my step daughter doesn't know that or her real father. she's never shown her any kind of affection or love. now her moods are unbearable every 2 or 3 days we fall out over stupid stuff like not getting the washing in or Ive said something wrong and she wont speak to me for 2 days, and then shes a happy lovely person.
Its honestly like I'm married to 2 different people and can change in seconds.
We have a 2 year old boy who she loves and show affection too and another baby on the way. This is why I feel so guilty for my step daughter
Please help
