Stepup, listen to Sandhi. I was like you being super nice, attentive, did everything for my W. She told me nothing was going on, just friends etc. Until i found hard proof. They will lie, lie, lie. They will lie like crazy, my W of 11 years turned into super crazy spy level liar.
Without hard proof, trust your gut.
