This is very hard stuff to cope with. @Sister is right, your husband is a grown up - problem is, he’s not acting as one. Dependency may have been present for a long time but becomes impossible when you can no longer carry the extra load. It may not be possible but if he has to cope on his own for a little while, it may shake him into realising that he has to take some responsibility - and resolution - about his own feelings and actions, not drop them on your shoulders. He needs some expert help, certainly, but getting him to that point of acceptance will not be easy. As suggested, a male friend or good workmate may be able to talk with him. Take care of yourself.
