Q&A How does one achieve closure from a marriage?

Hello...
My husband and I are about a month away from mediation. We've been married for 29 years. He had the affair, he filed for divorce, he's withheld information, lied, and continues with the affair partner. I have a lot of support; I have a great relationship with our 4 kids and receive a lot of love and compassion from them as well as from family and friends.

Besides therapy, prayer and acceptance (which I seem to be unable to achieve), is there anything else I can do to help myself along in the healing process to come to terms with what has occurred as something I simply can't change nor control? I believe it but I don't feel it. My thinking is rational but my emotions are quite irrational. : (
