The assertion that the children and parents on both sides want to keep her is a fallacious proposition. It should be noted that humans innately fear separation and thus invariably attempt to salvage relationships that are already untenable.
It is not the two families or the children who wish to salvage the relationship; it is you who desires to do so.
1. Is a child truly content when their parents cohabit in an emotionally sterile marriage? Children are perceptive, and even the youngest can discern the discord in their parents' relationship.
Furthermore, it is challenging to prioritize the care of children in the wake of the loss of a nurturing parent. The mere outward presentation of a harmonious relationship while living together can have adverse effects on children.
One must consider the following: if one wishes to depart from a relationship, yet is constrained by the presence of a child born of passion, how would one feel about that child?
2. The relationship is irreparably damaged, as evidenced by the fact that you can already cut the flesh from each other. A melon that is forced to grow will not be sweet; thus, it is preferable to allow each other to move on.
3. Divorce is the optimal solution for both parties. There are numerous incompatibilities between the two, and the respondent has experienced infidelity and abandonment by their partner, as well as the dissolution of the marriage and the subsequent neglect of their children. There is no compelling reason to maintain this marriage.
It would be preferable to resolve the issues of property division and child custody following a divorce, thereby creating a foundation for a future together, rather than continuing to cohabitate with incompatible expectations.
4. It is important to recognize one's own motivations and desires. In this case, it is evident that the individual in question does not want to give up the relationship. Their reluctance to let her go is not due to a lack of love, but rather a result of their long-term evolution and the inclination to maintain a relationship.
The key to authenticity lies in recognizing the underlying reluctance that often manifests as a mask of hesitation.

I can see this is really tough for you. It sounds like you're feeling torn between what you think is best for the child and your families, and acknowledging that your wife's heart isn't in the marriage anymore. Maybe it's important to consider what a healthy environment for your son would look like moving forward.
It must be incredibly painful to witness the breakdown of your marriage, especially with a child involved. It seems like communication has broken down completely, and her actions suggest she's made up her mind. Perhaps focusing on what will provide stability for your child might help guide your decision.
This situation sounds heartbreaking and complex. Your wife's proposal for divorce indicates she may have already decided to move on. Despite wanting to preserve the family for the sake of tradition or your child, it's also crucial to reflect on whether staying together in name only would truly benefit everyone involved.
The pain and confusion you're experiencing are very understandable given the circumstances. While you want to hold onto the family unit, it's clear that significant trust has been lost. Considering professional advice, such as counseling, might help clarify what path would be healthiest for you and your son.
