Flutie, Just wanted to pop in and say good luck to ya, love. I can't really offer any advice and, besides, you seem to be working through things just fine.
Perhaps your H is giving the hugs and kisses because he senses the internal changes in you..the resolve that is forming in your gut, to get a better life for yourself and your kids. Keep that your number one priority and let the chips fall where they may. If he decides to shape up his nitpicking act and be a part of your life, fine. If not, then it looks like you are mentally preparing for what that step will entail.
