How

Samuel - I so admire you and the work that you do. I wish I was 2 decades past my Unfaithful-ness. My infidelity came 11 years ago before my wife and I were married. It just came out nearly 3 months ago... my partner and I are separated with a divorce likely as I have other sordid and abusive behaviors to work on and make amends for. How do I get past my own ego? When my whole life's "work" has been ego-based and selfishness - my partner has been vulnerable with me and I spin and get defensive or trickle the truth or tantrum - all the stuff one is supposed to work their way through - and I can't seem to get past my own ego / get out of my own way.
