Finding time for me to post these days is difficult, but am always reading and trying to stay on top of this board. Sorry to hear of your life change,
you will get through it. I wanted to share this BabyCenter article with you http://www.babycenter.com/0_how-to-tell-your-child-youre-getting-divorced_3657057.bc?page=1
I thought it had some good ideas along with a more general article http://www.babycenter.com/0_how-to-talk-to-your-preschooler-about-tough-subjects_65676.bc?scid=mbtw_post4y_6m_3w:1286&pe=MlV3dkN4aXwyMDEyMDYyMg..
that might help anyone here.
