I'm sorry that things have gotten worse for you this past month. I think what you need to do is just step back and begin to solely focus on yourself and how you can build a satisfying life on your own going forward.
It is possible that after an extended break that your H will have time to work out his own issues and decide that one of the good things in his life was you and decide to pursue rebuilding your marriage. If that happens then at that point you will be a stronger more self confident person and can decide if that's also what you want as well.
It is also possible that after an extended period of time you or your H will not want to stay married. If that is the case you will be much stronger and more capable of dealing with the end of the marriage.
I know how tough it is to "start over" after being with someone for so long. I have been with my W for the last 17 years. However during the past six months I have begun to prepare myself for the end of this relationship and recognize that there is a better life for me out there. One not filled with suspicions, one not filled with a lack of commitment, one where I am much happier with myself and eventually with someone who appreciates me and is happy to be with me.
