Will you say more about the timing?
You seem to say your W started cheating after 22 years of M and that you discovered it after 8 years, so that means you discovered it after 30 years of M. You also say 'her actions 22 years ago'. Are yiu saying you got married in 1974, your W conducted an A from 1996-2004, and you discovered her A in 2004?
What did your W do after you discovered it? Did she do anything to change from cheater to good partner?
What did you do? You refer to therapists. Individual, mariiage counseling, individual counseling, sex counsleing - what kind of therapists?
What changes did you and/or your W change as a result of the therapy?
SI responses to a JFO (just found out) sitch is pretty cut and dried, because pretty much everybody is drowning. After 22 years, the BS's situation can be extremely varied, and the responses from Si need more info than in a JFO sitch.

You don't have to like your boundaries. You just have to set and enforce them.
