Yes they will be affected, but as long as they have you as a strong foundation, a person they know loves them and wants to be with them I think they have a good chance to come out ok. Constantly tell them you love them. When they do something good celebrate it. When things go bad help them work through it even if it just means sitting there while they rant. DO NOT say anything bad about their mom in front of them. As difficult as it may be they probably love her and if you bring them into your fight they will think that there is something wrong with them for loving her. It is a nasty thing. I wish you the best of luck in your case. I hope they rule in your favor.
Sincerely,
Zen
