Both, but the biggest for me: he has been straight-to-my-face denying the existence/continued R with OW1 for three years...up until I followed him last month and saw him with her (after seven months of no trips to her city). Lots of big lies all wrapped up in that one. I've also stumbled upon many things (i.e. existence of OW2's twins who could very likely be his) that indicate some very large lies of omission. He admits to being a compulsive liar.
