Friends DH left her for someone else when she was pg. He has been a complete twat for months and now said he can take his kids where he wants and he wants to have them in his city centre apartment and meet the slag girlfriend today. Says he wants them to live with him (think this is just a threat though). What can she do? Anything? She wants to go and confront the girlfriend today, I'm worried that she will batter her. Any advice gratefully received.
