I've made the decision. Now Don't know where to start. It will be an amicable parting with the complication of 2 young children. It's the agony of telling the children and the fear of loneliness that's holding things up. When do I know it's the right time?
I know exactly how you feel, it is overwhelming to think ahead. If you made the decision then there is no "right" time. Life goes on, take one day at a time. I always told myself that each day I stayed in a miserable marriage I was giving up happiness. I don't know how old your children are but the sooner you end an unhappy marraige the better it is for you and them. Have you discussed things with your spouse? The first step is getting a lawyer, they will guide you through the process.
Different people make decisions in entirely different ways. Think back to a less emotionally loaded yet important decision you've made in the past and try to use that as a template for making a decision here.
just my opinion, i knew my xwife and I had communication problems throughout most of the marriage, and knew that when the time came to explain to our daughters why we where getting divorced, that we may not of explained it properly or said the right words, it worried me, so I sought the help of a family counsler, kidzmatter of enfield, ct- we used the counsler as sort of a coach to guide us through such a senstive subject- it worked great, i still take the girls every other week, and although the divorce isnt final, my daughters are emotionally stable and have adjusted to mommy having a boyfriend and daddy eventually dating and moving on- (this has been over the course of about 1 yr)
