I don't know if this is the correct place to post because this is quite complicated! My step-dad (married to my mum for 26 years) has just announced that he is leaving her for another woman. My question is if I should let him see my children because I know my mum doesn't want me to but he was very close to them and my eldest in particular has said that she misses him. I feel caught in the middle of the situation. My mum says that if he sees them it will 'finish her' What would you do?
