So, husband finally came out and told me he cheated over a decade ago. It was when we were dating and have been happily married for a very long time. What’s got me sick and disgusted is that he messed around with his stepsister. Luckily they did not have intercourse. It was stupid and ridiculous because they both have attachment issues because of childhood issues. He never raised her or changed diapers and really she is not a true stepsister. She is simply his dad’s wife-daughter. I just need some wise words and encouragement as this has rocked my every sense of being and sense of self esteem. I have never felt so betrayed by the one person who I trusted the most. It’s like I do’t know who is since he spent over a decade keeping this secret from me. I am having PTSD because he told me all the details while we were both in crisis mode–angry–hurt–distraught…. I can’t get the images of those two fools together. I am on the verge of taking medication to take the edge off on the advisement of my therapist. We are also in marital counseling but it seems like I can’t get better. Has anyone been through something like this? Help…
