So imagine Peter walking out on Mrs Cephas and all the little Peters and Petras and he says "Don't worry I have left you the boat and the nets so you will be fine, I'm off to follow Jesus around Palestine and live on hand outs, maybe I will look in when we are next in the area."
You and Jesus see nothing wrong with that?
I don't know that anything happened like that at all... or if Peter even had a wife or children. They also stayed at houses belonging to some of his disciples, and ate at the houses of various disciples. So not everyone left their houses (permanently anyway); and perhaps some were given an ultimatum... stay with me and deny this 'apostate', or lose us and all of your possessions. As well, some still saw members of their families.
So we do not know the details, and we don't know that any woman or child was left to fend for themselves without support. I imagine that in those days, women were pretty good at tending the business of the families... especially if a husband must travel (for trade or for sea faring things or for war).
I do not judge or condemn people when all I have is a small tidbit, and there are other considerations.
Peace,
