Hi, Standing still is sometimes good. But other times it is time to move on. Your call, but it really isn't good to go on feeling as you do. Why not follow your dream, and if you don't have one, get one.
I am older than you, and divorced for the past few months, and much happier than when I was waiting around for my h to "wake up". Yes, he was hostile and mean to me, and yours seems distant, uncommitted and cold. Perhaps it is time to say enough, to tell your h that if he wants to commit he can come and find you, but that you are not holding your breath?
The sad truth is that some just do not wake up, ever. Think hard about what is holding you back from moving on? Hope, fear, inertia? I am not berating you, but just sad that you seem so unhappy, and dependent on what your h decides to do.
