Infidelity and lying going hand in hand. My stbxh could look me right in the eye, lie, and not bat an eye. I don't know if he was that good at lying or I just wanted to believe him so badly. Probably a combination.
Read up on "truth bias." We generally seem to want to trust and overlook a lot of warning signs. In hindsight we slap ourselves at how obvious and telling the signs were - but it seems to be the rule that most people here take the "My spouse would never..." line despite being given advice to the contrary.
Most spouses would. Not always being something they seek out directly.
