I don't know the answer to that either. Sounds like you did need some time on your own and you did mature during that time.
So should you give up the EA to get your H back? Yes. As a tradeoff, that's one that you should make. It's not an unusual requirement.
I suggest that you consider going to a Retrouvaille weekend with your husband. Check the website, http://www.retrouvaille.org for dates and locations. They have them all over the world. It is a wonderful marital retreat weekend that is not therapy. It focuses on improving your communication skills with your spouse.
Both EdieMarie and Limbo went to Retrouvaille weekends last week. You can read their threads and see how successful they were. You may have to push your H to get him there, but if you can get him there, you will almost certainly get good results.
