As a psychologist I hear of all relationship parameters. Some couples share expenses with each being responsible for particular bills while others pool their earnings with one person handling payments. Poor communication, reflective of unspoken marital issues, is usually the basic problem not money. Being a parent, of which the mother is the primary emotional caretaker in most families, is a full-time job when considering the need to get kids to medical appointments and activities, deal with their illnesses and maybe that of a pet too, food shopping, cooking and more, in addition to the demands of a job. Some keep three calendars: one for their job meetings, one for their kids' activities, and one for husband-wife events. I'm floored at the energy needed to successfully accomplish all and won't dispute those who regard women as the stronger sex.
