Husband falls in love with coworker

Two months ago, my husband of 22 years told me he’d fallen in love with a woman at his work. We’ve always had a balanced and loving relationship.

My initial reaction was understanding and empathy because I’m the only woman he’s ever been with. We are both 42, with two kids.

He’s devastated that he’s making me suffer and lost in this impossible choice. He can’t bring himself to leave me but also doesn’t feel capable of investing into our life together again.

I am trying to be respectful and understanding with him, but it’s taking a toll on me. I’ve lost 20 pounds in 2 months and don’t sleep well.

I believe in our love but he seems stuck despite seeing a therapist. I want to give him the time he needs to think about this, but it’s emotionally draining. I would like to be more serene in the face of this.

How do you recommend I approach this? Thank you!
