I've posted before about ongoing problems with my DH but I'm stuck in a rut and don't know how to get myself out of it. In short, my DH developed a MH problem (Delusional Jealousy) 2 years ago and we separated about a month ago. He hasn't been the best partner for the last 17 years but I have worked so hard to make the relationship work that I'm just devastated that it's all gone down the drain for no reason.
He is cold and distant because he believes I've been cheating, lying and putting him through hell when in all honesty, it's me who's been treated like dirt and abandoned when I'm at my most vulnerable. I know that his MH makes it real to him so he is suffering as well but he smokes funny stuff daily to keep him relaxed and is also on dopamine blocker medication. But he is in complete denial that anything could be wrong with him so that makes me the enemy.
I'm depressed, cry all the time and I feel lost and betrayed and broken. On the one hand, I want to stop contact all together aside from when we pickup and drop off the kids but on the other hand, he's a habit and I can't stop myself from calling/texting him when the impulse gets too strong. I've been emotionally alone for 2+ years and I'm falling apart. I'm getting regular counselling but I've just been on this mission to make him see the truth for so long that it's become an obsession. I want/need to talk it through with him - he never wants to discuss it again but I feel so persecuted that I am struggling to put it behind me especially when I still have so much love for him.
Help! How can I stop this self destructive behaviour before it destroys me more (if that's even possible)?
