Welcome! I'm glad to see your commitment here and your willingness to get busy working. It's good to see some of the posts from my fellow piecers.
We all know the tendency to obsess about our R. It really wears one out, so I think it's good for you to put some focus on yourself and your kids right now.
Try and see this from your H's perspective. He's hurt and unsure and not possessing the skills (at the moment) to help steer you guys back on a path of maritial happiness. Since you're here, you're in an ideal position to bounce things off here and get ideas on how to move forward.
