Point of dispute in our family. Db has left his wife and three children to be with his new girlfriend, four months ago. The children know her because she was introduced as a "friend" before he confessed and left. Since then the children haven't see her, at the request of my sil.My mother and of course my brother think it's unreasonable to wait much longer, but I am with sil in that I feel more time should pass. What do people usually do?
