Both times I cheated it has been driven by several issues

1 - a neurotic need to feel attactive (Im a bigger guy)
2 - I have a lazy bone, she would get pissed and yell at me which would in turn bring up my self-hate issues
3 - The self-hate issues became a pity party and insted of looking at her need, I focused on mine
4 - That focus, selfish in nature, intensified the neurotic need

I wasnt totally honest about the 1st A...she had to discover the truth herself and then drag the confession out of me.

This time around she discovered it and I laid it all out, I even called the woman I had the EA with while standing in my Ws presense and told th OW that I couldnt ever talk to her again becuase I had to be commited to reconciling and reconnecting with my W.
