I'm not in your shoes, so take this with a grain of salt, as with all advice, really
Since you're posting in the R forum, I'm going to presume you want to R. If your WF is not providing emotional support - then you aren't going to R. And what is hindering your healing, then, is being with an emotionally distant person who has hurt you and is not willing to aid you. And you're probably holding out hope that this will change. Healing is near impossible. There is probably no amount of outside support/coping mechanisms that are going to heal you if you're holding out hope for R in this situation. You just get crushed too repeatedly.
Sure, people stay in marriages like this for other reasons but, in order to heal in those situations, they don't even attempt R. They just co-exist.
So, as I see it, the only way to heal is to let go. Either get out or start moving that way. In the meantime, take care of yourself. Come up with other coping mechanisms (exercise, meditation, a new social circle, a class, a hobby, a good IC). But the REAL coping is only going to happen once you decide to let go of the M or the hope to R.
