Yes, agree Galaxy. We all know, or should know, that ideally children would live in a stable environment with two happy and supportive parents. However, for some people, and as Galaxy says, it’s often the woman, the need to separate is very real, in fact very urgent. All too often, one partner, usually the woman but not always, is in real physical danger, she may well have been raped, and she is under the control of her partner. It may not be ideal for the children, although it could be the best outcome for them.
And this is where caring and supportive grandparents, and other extended family members come in. They are able to provide the continuity of contact and care, and the stability that the children, and the frazzled and disoriented parent, needs. As the parent settles into her/his new life, the extended family members are still there providing that security, comfort, and unchanging love that the children so need.
