Sorry to hear about your Dad. I will say some prayers for him.
I agree with what AmyC is telling you - deal with you and your girls. Let all of your worries about your H go. Your H is not ready for you and it seems anytime he is around or his says he will be around or call - you get a little "Wacky". Look back in your posts - you will see. When he is away from you you feel better, more independent, more focused on you. Anytime he says he calls and then doesn't or is supposed to stop by - you start obsessing and getting crazy....
It's okay, my W drives me crazy too ! But look at this no contact time as a time for Emily to build a stronger Emily - one that cannot be taken down by any word or action that your H does or says he will do. I think later down the road you may have a chance to make a decision about your R/M - but right now you don't. You may even find later that he simply is not for you - because he won't change. Unfortunately he has to want to change and quite frankly - he doesn't have it in him now.
Stay strong angel! You sound better and I hope you keep this momentum going. I will pray for your Dad.
