Kat, honey, I'm concerned for you. You need to accept this and turn your back on him. I know you're hurting and I understand, but you have to be responsible for yourself and that means not allowing H to have control over your own self-worth.
What does it tell you about H that it is ending in lies and betrayal? That he was not the person you thought he was. That you shouldn't be putting up with him. You have dignity and integrity - it's time to bolster that within yourself.
The infidels try to make us feel guilty for their sins, but that's just ridiculous. We shouldn't feel bad about ourselves because of them. We should rejoice that we're better than that.
I had hope too. I still have hope, but I'm not going to let that hope cloud my vision any longer. The thing with DB is that the techniques are great, but if there is an A, the other person HAS to WANT to work hard to preserve the M.
Here's a link to something that helped me and maybe it'll help you. I hope so because I hate to see you hurting like this. I know why you are and I'll probably be in the same spot when my D is final in October. Anyway, FWIW:
