Welcome to the community :)
At this point it is about her. About what she needs and wants...regardless of what that means for me.
That’s a really common, and usually very necessary, core component of reconciliation. Neither it, nor the other common pieces (total transparency, etc. that are part of rebuilding trust) guarantee reconciliation, but the definitely increase the odds of it.
There’s always a line, but a good couples counselor will help you be able to mind that line fairly easily. There’s a big difference between rebuilding, punishment, and abuse.
People unfamiliar with infidelity often miscatagorize rebuilding as punishment or abuse, or the opposite, and see punishment and abuse as rebuilding.
That’s part of why a skilled impartial observer is so durn useful in helping couples learn to identify and navigate those lines.
She then called my wife back the next day and said "I don't think I can. I think your trauma is too great for me." So my wife has been very reluctant to find another.
That’s actually a good thing.
PTSD is one of the “big” disorders (like autism, adhd, bipolar disorder, dyslexia,etc.) That needs specialized treatment, rather than generalized treatment.
Sexual assault doesn’t need specialized treatment in and of itself. A marriage and family therapist (MFT) will usually deal with loads and loads of sexual assault that has affected peoples lives in different ways that
doesn’t progress to having caused a disorder in their practice. Once it
has progressed to a disorder, the ethical ones won’t attempt to treat it, as its outside of their skill set, but will refer them on to a specialist.
The exact same way a reading tutor will teach a lot of people with reading difficulties to read, but refer dyslexics to a specialist; a GP will treat a lot of blood pressure patients, but refer serious heart problems to a Cardiologist; etc. It’s about getting someone the best care, by the best trained people.
Ethical MFTs will refer Trauma Clients onto Trauma Therapists

What you and your wife are probably going to looking for is something called a “Trauma Informed MFT” (for the both of you)
This is someone who is educated enough in trauma to be able to treat the Marriage & Family problems
without stumbling face first into trauma issues, rather than attempting to do both MFT & Trauma.
Lots and lots of MFTs specialize this way. Whether it’s trauma, childhood disorders (autism for example), medical conditions (cancer for example), etc... they’re very practiced at understanding there are different issues in play, that they work around / leave to other professionals, and consider themselves part of TEAM treatment. They do what here good at, and work in a structure that accounts for other major issues in play.
AND (maybe... depending on whether she actually needs trauma therapy, or whether the infidelity & stress has simply kicked her symptoms -that she’s well versed at dealing with) A Trauma Therapist for herself.
OR ... A trauma therapist who also does Marriage and Family Therapy. Although this tends to be rarer. Trauma Therapy is a specialty that takes several years longer to acquire than just an MFT license, so whilst it’s common for trauma therapists to work with families in regards to trauma, it’s rarer for them to set their specialty aside to work on couples counseling. It does happen. It’s just not super common.
