Hope- I am so happy to hear that your H may be realizing the error of his ways, and coming to terms with the issues behind his behaviors. Think about how you felt when you came back from your visit with your family, before this interaction with your H. That is how you have to continue to act until he makes a commitment to you. He has dangled the carrot in front of you...don't be too eager to grab it. Try to stay detached. Its a delicate balance. But, i think you can do it. Don't push for too much right now...just take what he is giving you.
