ptsd triggered by schizoid husband

I have been in intense therapy for 5 years for PTSD from childhood ritual and sexual abuse. I am actually experiencing light at the end of the tunnel...even though I know the tunnel will never truly end. No more trying to self destruct, at least for now, depression is being managed well with meds, sleeping with meds, but altogether functioning better than I have in years.
I have always been the "problem" in our marriage, but after doing all of the hard work I am have now discovered my husband has Schizoid Personality Disorder.
Our conversations have been triggering me something fierce. It is the feeling of abandonment, rejection, and when he completely closes down the fear starts rising up again.
I had dissociated for several years and everything had integrated, and now I am experiencing levels of regressing into "little girl" and "teenage girl".
I have fought long and hard to get here, and I am determined not to go backwards...
He has never been willing to go to counseling with me for anything, but is actually going this Friday with me. I don't know what good it will do, but I am praying that something will motivate him to continue and see the value for himself.
Thanks for letting me join in the group and vent. Feedback is definitely welcome.

Only recently realized I have PTSD in the mix with BP-II, major depression, anxiety. Have only just entered the "pandora's box" phase in therapy, which has increased anxiety level, but hopefully worth it... you give me hope! Kudos for sticking with it and becoming functional. It is huge. Give yourself tons of credit when you can. That said, it's also HUGE that he's going to a session with you. One session might be the difference but seems to depend a lot upon how your T handles it. Prayers that you're able to get somewhere with this person.. he needs to recognize, understand and accept his own thing before he can do so with you, maybe? Meantime go easy on yourself and forgive him his lousy behavior... he's ill and you can help him and each other. Peace.. Alex.
