For me, I tried for about a month and I do believe my xh is in a full-blown midlife crisis.
I listened to my inner voice which told me he and the ow were hiding assets from me and I filed right then and there. As legal proceedings went on, sure enough...hidden money.
Also, I went to an "intuitive" (psychic)which I was skeptical about, but she gave me amazing information that really helped me close the door on some things. She told me to be "true to myself" and for me that meant I would never be able to trust him again and would not be able to live with the thought of him sleeping with someone else. Period.
So, I've accepted what I did towards the demise of the marriage and moved on. I'm not interested in being with someone who doesn't want to be with me. IMHO, some people hang on out of "fear" which is completely understandable and I know I did that as well. But, who wants to live his/her life in fear all the time? In fact, "Fearless" by Taylor Swift is my ringtone and how I chose to live my life.
