RW, I hear you loud and clear. I do think you are entitled to that anger, particularly because your H has totally put you on the back burner to "deal with his own issues." Has he done anything to address the marital issues? If not, you should think about what you expect from him and lay down the boundary.
"H, I will not continue in a M where only one person is working on the R. I want and deserve a partner who is going to make this R a priority. I understand that you wanted to work on your personal issues first and I have given you time and space. However, my patience is not unlimited and I will be making decisions about my future soon."
Then continue with your PMA. Don't give him a time table but set on in your mind and see if anything changes by then.
And don't worry about what your daughter said. She's 13, things are much simpler before real life. You're teaching her (if/when she learns the truth) that M is a serious commitment and you are doing everything you can to honor that. If your H doesn't step up and do the necessary work then you show her that a woman doesn't have to settle. You move on with your life and find someone who treats you as you deserve.
If you love somebody, set them free. http://tinyurl.com/2empx2g
