Saturn... Crying is an outlet for pent-up emotions and a "good cry" can do wonders.Be glad you have that outlet.
I am wondering why you tell H "you believe in him, etc". IMHO,you should work on some "active listening" techniques. Just listen to what he says and repeat/rephrase. He doesn't want to hear positive things bout your relationship, at this point. You can't convince him of anything. You are right, he has to come to realizations on his own. Keep detaching...look wonderful,do things for yourself and continue to wait. When My H would tell me he wanted a D. I would just listen..and say "So you think we should D,I'm sorry you are so unhappy" and then I would just drop it. I got more info from him and made him think more,by just listening and validating what he said.
