I don't think the problem is with disclosure; as you said, women encourage it in relationships. I think the issue is a misalignment of expectations/needs occurring when one party feels they are doing the bulk of caring work/emotional support, but it is unreciprocal. I recall reading this somewhere.
@πππππππ πππππ has a point when she says women end up serving multiple roles of relationships-maintenance expert; therapist, motivational coach, cheerleader, support worker/caregiver. Women do most of the heavy lifting emotionally, even when both parties are equal professionally and 50:50 in the division of finances or tasks.
Perhaps it is a matter of fit; some women are primed more for this. However, I think even for highly emotionally attuned women who like showing concern and caring for others. They may even experience exhaustion from over-extending themselves. It is almost expected for women to be overly self-sacrificing. A problem arises when a woman forgets her individual needs, wishes, and goals and invests her energies and time in caring chiefly for his.
