If there is an EA, that will change things a bit for me. If there was a PA, that might be a deal breaker. I went through a divorce after wife's PA before after trying to work it out, I am not going through that pain again.
If that's the case, then I suggest you find out (independently -- she will lie to you, if she is) and then figure out what you want to do. I'm not trying to alarm you, but everything that she has said about the matter is pure "script".
