Is this Self sacrifice?

The motives behind injudicious giving and destructive nurturing are many, but such cases invariably have a basic feature in common: the “giver” under guise of Love, is responding to and meeting his or her own needs without regards to the spiritual needs of the receiver.
Layman tend to associate sadism and masochism with purely sexual activity, thinking of them as the sexual enjoyment derived from inflicting or receiving physical pain.
The most common and serious kind of social sadomasochism, in which people unconsciously desire to hurt and be hurt by each other through their non-sexual interpersonal relations. Proto typically a woman will seek psychiatric attention for depression in response to desertion by her husband. She will regale the psychiatrist with an endless tale of repeated mistreatment by her husband. He paid her no attention, he had a string of mistress, he gambled away the money, he went away for days for days at a time whenever he pleased, he came home drunk and beat her, and now finally, he has deserted her and children on Christmas eve.
The neophyte Therapist tends to respond to this to this ‘poor woman’ and her tale with instant sympathy, but it does not take long for the sympathy to evaporate in the light of further knowledge. First the Therapist discovers that this pattern has existed for over twenty years, and that while the treatment has existed for twenty years, and that while the poor woman divorced her brute of husband twice, she also re-married him twice, and that innumerable separations were followed by innumerable reconciliations. Next after working with her for a month or two, when every thing seems to be heading the right direction, when the woman seems to be enjoying the tranquility of life apart from her husband, the Therapist sees the cycle enacted all over again. One fine day the woman bounce happily in the office to announce “Well, henry’s back. He called up the other night, saying he wanted to see me. He pleaded to me , saying he wanted me to come back, and he really seems changed , so I took him back. ”When you point her that this seems to be a repetition of the cycle, which she had earlier agreed was destructive, she says, ”But I love him. You can’t deny Love.” With strenuousness the patient terminates Therapy.

What is going on here?
In trying to understand what has happened, the Therapist recalls the obvious relish with which the woman had recounted the long history of her husband’s brutality and mistreatments. Suddenly a strange idea begins to dawn: Maybe this woman endures her husband’s mistreatment, and even seeks it out, for the very pleasure of talking about it.
But
What would be the nature of such a pleasure? That Therapist remembers the woman’s self-righteousness. Could it be that the most important thing in the woman’s life is to have a sense of moral superiority and that on order to maintain this sense she needs to be mistreated? The nature of the pattern now becomes clear. By allowing herself to be treated basely she can feel superior. Ultimately she can even have the sadistic pleasure of seeing her husband beg and plead to return, and momentarily acknowledge her superiority from his humbled position, while she decides whether or not to magnanimously take him back. And in this moment she achieves her revenge.
When such woman are analysed it is generally found that they were particularly mistreated as children. As a result they seek revenge through their sense of moral superiority, which requires repeated humilation and mistreatment. If the world is treating us well we have no need to avenge ourselves on it. If seeking revenge is our goal in life, we will have to see to it that the world treats us badly in order to justify our goal. Masochists look on their submission to mistreatment as Love, whereas in fact it is a necessity in their never-ceasing search for revenge and is basically motivated by hatred.
