Jenny, so sorry to hear what your H had the gall to say to you. You deserve so much better as do your kids. You are strong and I know that you are going to be the one smiling and happy at the end of all this.. not sure if your H will be standing next to you or not but if he is... he better count his lucky stars that he's got such a wonderful woman.. if he's not, you will be happy with yourself and will start a healthy and happy R with someone wonderful - when you feel ready!
I hope the birthday party was great! Can't wait to hear how much fun you and your D had!
