Yes. Gut feelings can be wrong. That's why the scientific method exists and we don't rely on gut feelings when seeking as close to an approximation of absolute truth as we can achieve. It's the most logical way to find it.
However, this isn't science. It's not logical. You're in the realm of emotion and emotions are messy and don't always make sense. Gut feelings have been pretty accurate for many here on the forums. You subconsciously pick up on things that don't add up and they eat at you. How accurate was your gut feeling the last few times?
I gotta say, the fact that she keeps lying to you and you keep forgiving it does not incentivize her to be honest and stop what she's been doing. It seems a little bit pick me dance-y. That never works. You have to stop being afraid of losing her if you do or say the "wrong" thing. You already lost her when she cheated on you. If you questioning or being upset over her actions causes her to leave then just how strong is the relationship? Do you want to stay with her if you feel like you have to walk on eggshells and deal with these humiliating discoveries for the rest of your life?
It's counter intuitive, but sometimes to save a relationship you have to be willing to let it go. You don't want to be with someone who isn't committed to you. Sometimes a 2×4 upside the head is what it takes to snap a wayward spouse out of the fog. When I called divorce lawyers in front of my wife it changed everything.
It turns out she didn't want to lose the marriage and was willing to do whatever it took. Including going no contact and being honest with me. I know her passcodes and have unfettered access to all of her devices and she's completely comfortable with it now. She wasn't before. It took a hard dose of reality to get her there. I don't know your wife. It may not go that way for you, but there are many other stories here with similar results. I'd rather risk losing her than live in infidelity. That should be your goal. To get out of infidelity.
There are 2 paths for that. Divorce or reconciliation. Reconciliation has to be built on truth and transparency. If not, then divorce is the other option. Not the preferred option, but it's better than living with a cheater. You have to find your resolve and force some action. I hope you do, and I hope you get the outcome you want, but in either case you have to decide you're getting out of infidelity one way or another. For me, that decision saved my marriage. And my sanity.
