Lynn, you have so much on your plate. Put this whole issue of your stepfather on the back burner and don't pick it up again. It took you your whole life to get to this solid ground...please, my beautiful Lynn, don't let him steal even another moment of your life away. Don't let him guilt you, don't let him stress you, be firm and BE OKAY with knowing that you've done all you can do (and so much more!!!)

There just comes a moment in our lives when we're allowed and must say "enough". Draw the line in the sand, and know that it's essential for your own health and well-being to do so. Hugs.
