Drowning, I’m so sorry this has happened to you. What a nightmare.
You’ve only been in this for one week, so here are some practical things you should do:
1) Take care of yourself physically. That means making sure to eat (we all know you’ve had no appetite since you found out); staying hydrated; and importantly, getting exercise. You’re probably having trouble sleeping. Exercise will help with that. If it’s not enough, talk to your doctor about sleeping pills. Also talk to him about anti-anxiety or anti-depression medication as well.
2) Get an STD test. If you WH is taking PrEP, then you need to be tested too. I assume he’s getting tested? Insist on seeing the results from him, don’t let him tell you he’s clean.
3) Talk to a lawyer like the 1stWife said. Right now you have a lot of fear of the unknown future. So start removing some "unknowns". Talk to the lawyer to take the mystery out of it. You’re not committing to anything, you’re just learning. Ask your lawyer how to protect your assets. Obviously your WH is very good at hiding things from you. You need to have access to all your financial accounts.
4) He needs the right kind of help if he’s a real sex addict. There was a recent thread here by a woman who discovered that her WH was an SA. I’m copy-pasting some advice she got:
He needs a CSAT ( therapist who deals with sex addiction )
With csat a therapeutic disclosure followed by a polygraph ( don’t skip this part and your/ his csat can recommend one )
Treatment
Sex addiction is highly treatable but he must do the work. It’s a boundary you set - "I will not make any decisions right now IF you do the above - if not it will show me you aren’t committed to healing "
For YOU
STD testing
Support from trusted friends
Apply to become a member at WeTonglen a vetted online resource and support for betrayed spouses and steps u need to take. You needed a betrayal trauma coach or therapist. WeTonglen has free webinars , daily online support groups. This is where u need to be
Recovery is possible but it’s a lot of hard work. Takes 3-5 years. You are in the worst part know - I’d say first two yrs
Lastly , sex addiction affects you but is not about u. He can love u and do this. It’s not even about sex , it’s about dopamine and probably his trauma.
5) It looks like you’re instinctively applying the 180. The 180 is good for protecting you emotionally, and for removing your emotional dependence on him. For more information, check out the Healing Library. You also need to see a therapist yourself. Find one that specializes in betrayal trauma.
6) If you’re not comfortable being around him, then don’t let him come to the Lake. I personally think it’s good for him to suffer some consequences for his 20 years(!) of betrayal.
7) I’m glad you already know not to trust him. He’s clearly continuing to hide things from you. You’re thinking about giving him another chance, but you can’t do that without a full accounting of what he’s done. You can’t forgive what you don’t know.
Here are two threads for you to read though:
Pugnamedyoda’s, which I already quoted from: https://survivinginfidelity.com/topics/666893/husband-cheated-on-me-with-escorts/?ap=1
Sigyn’s thread. At this point we have to be concerned that your WH might be like hers. https://www.survivinginfidelity.com/forums/?tid=658109&HL=80576
