Have a brief read of this snippet from a book written by Michelle Langley in 2005: Women's Infidelity

Just to give some overview, Michelle Langley is a career development specialist that underwent a phase of infidelity in her marriage, and wrote about the process. What she has written is a culmination of at least half a dozen major TRP tenets.

She describes how women marry men they're not attracted to, but still have lust for men outside of their marriage:

They have all the things that they wanted—a home, a family, a great husband—but they feel they should be happier. Over time, many women in this stage begin to lose interest in sex. It is not uncommon for them to spend a great deal of energy trying to avoid physical contact with their husbands because they fear it might lead to a sexual encounter.
Women at Stage 2 experience reawakened desire stimulated by an encounter outside the marital relationship. Whether these encounters with a "new" man involves sex or remain platonic, women will typically give a tremendous amount of emotional significance to these encounters.

She talks of how women will hamster away negative feelings, choosing justification over facts:

Women in this stage can no longer express their prior disdain for infidelity without feeling like a hypocrite. They feel as though they have lost a part of themselves. Reflecting society’s belief that women are either “good” or “bad,” women will question their “good girl” status and feel that they might not be deserving of their husbands. Many will try to overcome feelings of guilt by becoming more attentive toward and appreciative of their husbands. However, over time many women will move from appreciation to justification.

And here she talks about how women absolve themselves from responsibility, and play the victim:

Women in Limbo I are at a crossroad. Here, they will either begin to grow and develop a deeper relationship with their husbands, or they will stunt their growth with feelings of anger and resentment over not attaining the happily-ever-after feeling they had anticipated. Women in this stage are faced with the dilemma of either taking responsibility for their lives or choosing to view themselves as victims. If they choose to view themselves as victims they will eventually move into Limbo II.

Initially, many of these women are completely guilt-ridden over cheating. Women can easily recommit to their marriages at this level if they forgive themselves. However, forgiving themselves requires taking responsibility for cheating. So, once again, these women are faced with the same dilemma they were faced with in Limbo I. They can either take responsibility for their lives and their behavior or they can continue to view themselves as victims. If they choose to view themselves as victims they will eventually move into Limbo III.

Given that this was written in 2005, years and years before TRP existed, and by a woman no less, how much validity do you still place on TRP simply being a bunch of angry, misogynistic men who are lashing out against women? This strongly suggests that TRP knowledge is simply true, and possible for any outsider with sufficient motivation to come to the same conclusions.
