While I agree with the general sentiment here, I want to emphasize a few points.
It's impossible to offer specific advice without knowing the context—your story, what you did, and why. However, your current feeling of self-hatred is the most immediate consequence of your actions.
For change to happen, a person needs to face accountability. When a partner chooses to stay after infidelity, the traditional external consequence (a breakup) is avoided. This makes the self-hatred you feel incredibly important; it's the internal mechanism that holds you accountable and fuels your drive to change into a trustworthy partner.
I don't believe that "anyone could cheat." Infidelity usually signals a deeper issue that needs to be addressed. Your goal now is to channel the intensity of your self-hatred into constructive action—therapy, sincere communication, and consistent behavior—to prove to yourself, as much as to your husband, that you are capable of fundamental change.
the occasions where a BS makes a negative comment or assumption about all WS in general seem to really make me bristle. I find myself having imaginary arguments with the posters in my head for much of the day. I was trying to figure out why that was happening, as it’s very disruptive.
Perhaps I am wrong, but this opinion seems to stem from a failure to fully grasp the severity and uniquely damaging nature of infidelity. To many, it represents the most devastating legal offense one can commit—an act of betrayal that wounds a loved one to the deepest possible extent, functioning as a form of prolonged psychological abuse.
I do not fully understand your logical premise regarding the treatment of cheaters. What is the appropriate response a betrayed spouse or society, for that matter, should have toward those who commit betrayal? Do you not believe that negative commentary or moral condemnation is justified when addressing such a profound violation of trust?
The final point is that this stance of non-judgment could easily be extended to any person who has committed an immoral act. Should we, as a society, refrain from being critical of con artists or thieves? And would it truly be reckless to make certain assumptions about the character of individuals who willfully cause such harm?
I think it might be because I have a deep need to feel like I’m a good person worthy of love and marriage
Don't we all. My recommendation would be to begin working on acting in a way that's worthy of these things. I don't feel cheating is an example of such worth
I hope you find happiness
