i might suggest to mom that she's better off selling her mansion in the burbs and downsizing to something more appropriate for her new life as an ex-mom. she may find she's saving money on travel costs, as well. it's unhealthy to cling to the past; it's time to move on.
and, to the lady that wants some muscle to protect her, she might be better off posting an ad in the classifieds, if she feels like that's what she really wants. but, she might want to drop the entitled attitude that suggests her partner is obligated to fork out $50/week. that, itself, might be the reason she's posting an ad like this in the first place.
