I am so sorry, Hopeful, but good job for being strong and not answering even on a day when you are feeling especially vulnerable! Your AXBF is not missing out on this because of you, but because of his own actions. And for your girls it will be the best thing to share this day with YOU, not with someone who is using -- so way to be a great mom!!
I know that doesn't make it any easier when we wish we could share moments . . . . Stay strong and enjoy trick or treating! And let us know what your little ones are dressing up as!
