Hi, from everything i read, it gets worse before it gets better. people grieve broken relationships, even if they are no good. this is how the brain processes loss. i'm not even divorced yet and going through couple counseling, but it hits me hard. i'm very sensitive, emotional, and susceptible to depression, and that makes it extra hard for me. IMHO, a singular infidelity is not a reason to break a relationship. people learn a lot from those. Are you familiar with the "the state of affair" book by Esther Perel? its on audible too. it helped me a lot. it was recommended by one of my therapists. of course, your situation could be very different. please tell.
