Good luck with therapy! If this is couples therapy, I think the best thing you can do is take ownership of how your behavior and issues impact the marriage. And she needs to do the same...every person has issues and it takes two in a relationship.

She understandably is hurt and the therapist can help validate that....let her be upset and you need to take ownership of how you played a role in causing the rift in your marriage. Express that you are sorry, you love her, and you want to regain her trust.That, I think, will open the door to forgiveness and reconciliation.

I hope it's couples therapy. If not, please disregard lol
