Several things to consider right away:
Get a FULL panel of STD testing, and tell the Dr you believe your spouse has been having a PA. No matter what a WS says, we have to protect our health, and our WS have shown us that they are good liars (can't tell you how often we see it on SI -even the WS themselves - swearing on their children's lives it wasn't a PA or they used condoms, or a host of other crap, only to learn they were lying the whole time). Maybe it was solely an EA... maybe not. Protect yourself.
Meet with an attorney. Knowledge is power. f you don't want to R, then you will be taking steps on your own behalf. If decide you want to try to R, you still need to know what your life would look like. The old saying "you have to be willing to lose the M to save it" rings VERY true IMHO.
Find an IC (individual counselor) - and my rec is always to find someone who really specializes in TRAUMA (vs infidelity). Someone that's graduated in the last 10-15 years (after the schools made learning about trauma a requirement for anyone on a clinical path). You can educate yourself (and your IC, if need be) about the nuances of relational betrayal trauma (or infidelity). It's the trauma that changes us, not the infidelity itself (hope that makes sense).
Find some self compassion. You may already be there, yet I sense you may be kicking yourself a bit (the "how could I be so blind" or "how could I have a bad picker" kind of thing). I - and so many BS -spent quite a bit of time kicking myself in the aftermath of dday (the "how could I be so stupid, blind, etc" rang over & over & over in my brain.. I am a highly educated professional whose nickname was - literally - "badass", so I get how we can fee sooooo duped and it can shatter parts of our identity).
There may have been red flags (e.g., that your WH cheated before .... same as mine, btw), and for whatever reason, we didn't see or ignored or whatever. It's hard to look at parts our ourselves that need some work if we hate them / hate ourselves. My point is that IME, the path to healing includes a healthy dose of self compassion and pivoting. We can pivot from that self anger to self love and compassion, and that, IME / IMO, is the path to changing our perspectives. Another thing that I think some BS (maybe including you, maybe not) may do is pivot the anger with their WS to themselves. And I believe that anything we can do to not take it on ourselves and then work to release that anger in a healthy way will aid our healing.
Trust? Yeah, it probably won't ever be the same. It's very heartbreaking to say that, knowing how hard it is to hear or think about. I think the trade off (so to speak) is that we learn to better trust OURSELVES, and we heal and get stronger so that we are able to again take risks, and know that even if emotional risks don't pan out as we'd hoped, WE will be OK. It takes some time. We felt safe in that trusting relationship, where we didn't question our vulnerability bc we believed our WS had our backs. And I think we can and do feel safe again (whether we R or not - I'm not in R), it's that we become more safe w/in ourselves vs in a relationship.
And finally, I believe that telling the OBS (other betrayed spouse) should happen regardless of whether you are - or are not- ultimately interested in R. This is an oft-debated topic, so there is no universal "right" or "wrong" thing to do. Just giving my personal opinion that even if the motivation is selfish (eg you want the AP to hurt), telling the OBS is the right thing to do. My sole caveat is when telling OBS may cause further damage you (eg if OBS told HR about the A, would your WS be in danger of being fired? And how would that impact YOU right now?). HOWEVER, I do believe that even if telling the OBS may need to be posponed, it should always be done the minute the danger has passed (eg if your WH changes jobs, once the D is final, etc). IMHO, there is NO statute of limitations on telling the OBS.
I'm sorry you need SI, but am glad you found the "best club that NO ONE wants to belong to". Welcome.
Godspeed.
