A relationship can only be sustained so long as the woman’s hypergamy is satisfied, this drives may women to make the situation intolerable for both herself and her partner. The only other time that a relationship can be sustained is if she understands and overcomes her hypergamy in some manner. This requires introspection and responsibility on her part.
A womans hypergamy can drive her into nagging her man, and feeling dissatisfied with him that he is not the man she envisioned. She will start seeing him as doing everything wrong and make sure that he is constantly in a lose/lose situation to punish him for not being the man that she believes she is entitled to.
The lack of her hypergamous desires being satiated leads to her becoming bored with that man, she may lose previously held feelings towards him and feel guilty about it, or simply come up with a neverending lists of miniscule things that are wrong with him in order to rationalise it.
