I am so sorry you had to find us, Youngblood. But this is a great group of people who truly understand what you are going through like no one else. And it sucks. You will hear from folks with experience and you may hear things that you do not like. Please take what works and leave the rest, but also note that sometimes it is the things that tick us off that are the things we may be deceiving ourselves about. In the end, you know your situation best, and we can only reply to what we read.
That said, an EA is just as bad as a PA. And to many, making out IS a PA. (And were there other acts, not just actual intercourse?) Did you see the test results from the polygraph? Very unusual for a WS to take that step unprovoked. And so many WS minimize their actions - just a kiss becomes oral sex becomes…. They are trying to tell you the bare minimum and diluted version of the story. Not saying she is doing this, but it happens a lot.
The increased sex may be hysterical bonding (google it to learn more). Enjoy it - it doesn’t always last, unfortunately. But it is a way of "claiming" you partner and is totally normal.
And your emotions will be ALL. OVER. THE. PLACE. We call it a roller coaster because you will be whipped around by emotions for seemingly no reason. Your brain is trying to process what it believed was the truth of your past and compare it to the reality of your past and it is very hard. You start to question everything you thought you knew - was it real? Was she being honest? It’s a mindf*ck and it takes a long time for your brain to sort out. You will ask the same question over and over again as your brain tries to verify what it knows and what it doesn’t know. All totally normal.
Have you and she had full STD/STI testing? This is 100% required, even if she says she didn’t have sex. You just can’t risk her minimizing any interaction. Also her willingness to get tested and share the results with you will show you her dedication to helping you feel safe.
Glad you are in the gym. Keep that up. Taking care of yourself physically will help your emotions. Eat well, drink lots of water, avoid drugs/alcohol, exercise daily, and get enough sleep. If sleep or anxiety are a problem, see your doctor. (Maybe while getting that STI testing…) If you can’t eat, try protein shakes to help. The unintentional infidelity diet can be rough.
See a lawyer or three to understand what D might look like- not to file. Knowledge is power, and by understanding what D might look like will help you from making decisions from a place of fear and uncertainty. It can also help you avoid making decisions that can hurt you later if things end up in D. You don’t need to tell her - this is to help you have control.
Who are you talking to IRL? Confiding in people who will support you whether you R or D can be extremely helpful. IC (individual counseling) can also be a life saver. Look for one who specializes in trauma. Family, pastor, bestie… you need an outlet. Journaling can also be very therapeutic.
Remember that NOTHING you did or didn’t do as a H caused her A. There may be have been areas for improvement - no marriage is perfect - but having an A was her choice and is 100% on her. She had many other options if she was unhappy - cheating was the most destructive one and she chose that. Do not let her use the word mistake - mistakes are forgetting milk at the grocery. She made many conscious decisions.
Lastly, your emotions will ebb and flow. Once the shock wears off, you may be numb. Many of us go through a rage/anger phase, sometimes around the 6 month mark. Others describe a POLF (plane of lethal flatness) in year 2 as the reality of the whole thing finally settles in.. it wasn’t a bad dream and we can’t go back to life before the A. So expect changes.
Oh, and be sure to pay more attention to her actions and not her words. It will take consistent actions over time that will help you see if R is possible. And think about what YOU need to feel secure. Have her read the book "how to help your spouse heal" by Linda McDonald. Read it yourself, too - short but good read.
Hang in there and keep posting. Do you have kids? What ages? Family nearby? Good jobs? Has she changed jobs (which if she works with an AP then that should be required)?
You WILL get through this. Thousands have sadly walked this path before you. Some R, some D, some stay married but not in R for a variety of reasons… but all survived. Hang in there.
