I'm finding this a very difficult problem. My friend has a 10-yr-old daughter and 7-yr-old autistic son. Her partner, their father, is very volatile and can be cruel and play mind games with all 3 of them. He isn't English and I think his cultural background predisposes him to a different set of 'rules' when it comes to his parenting. He sees himself as solely a breadwinner, seems to resent my friend going out in the evening, spends very little time with his children and seems to belittle all his daughter's achievements. I know he has smacked his son in the past when he has wet/soiled himself - and put him under a cold shower to 'teach him'. I know also that he does a lot of shouting. Last weekend my daughter was at their house and witnessed this man slapping his daughter across the face twice for not doing what he'd asked of her. She was naturally very upset and told my DD that he had slapped her before. I picked my DD up some 5/6 hours later and there was still a red mark on this girl's face! My friend has passed the whole thing off as not being significant, saying her children are not in danger and that it was only a slap. This, in itself, is very worrying as I wonder how used to this behaviour they've become. I feel she is in denial - the situation is complicated and she is financially dependent on her partner so would find it hard to even threaten to leave. (She may have feelings for him, despite what I may think of him.) But I think she is burying her head in the sand because it's too hard to deal with - and she's hoping for some miracle change in her partner. I don't want her to feel I'm bullying her and I don't want to take it any further (i.e. to social services). But, if she won't deal with the situation and try to stop the abusive behaviour, where does that leave me? My daughter values her daughter's friendship (they've known each other since they were babies) and I wouldn't want to just turn my back on the situation and pretend everything's OK - that would be easier maybe but cowardly. But I really don't know what to do in the best interests of the children. Does anyone have a similar experience? What should I do?
