I'll try and give a quick update. I'm now not sure what I should be doing next. Any thoughts.
I was planning to expose to ILs but they know now because of the Monday night events. W has already twisted me into the crazy guy who recorded her conversations. I blew it a little by interrogating as W denied. The following night I reiterated my boundaries and W just denied some more.
I really don't know what to do next. I have to think something is still going on W is still holding her phone on her at all times and now hiding her laptop.
BWP,
As I think I stated previously, I think you need to just proceed on the assumption that your wife IS having an affair. There's certainly nothing in her current behavior that would indicate that she's ended it, and I don't see any reason why your lack of voice recordings should change your tactics:
GAL, continue to be "the better option," but begin to do what you need to do emotionally, legally and financially to move on.
I would just exclude the in-laws at this point from any "exposure," as she seems to have them spun and gaslighted, and they're not being supported. If they ASK you, or continue to challenge you, then by all means say something like "You can continue to ignore what's going on, but I need to do what I have to in order to protect myself and my family."
