This is my first post, I was compelled to reply as I went through this exact thing with my DP last year. It?s a long story, but hopefully my experience may help. DP is a jealous person and always has been, but I knew early on what he was like and decided to work with it anyway, as everything else is so right, I could live with that flaw. 6 years down the line his jealousy over stepped the mark, it happened last summer, when our DS was 18 months old, all of a sudden he became obsessed with my past, would question me for hours, search the house for god knows what, call me names, cry uncontrollably, would follow me, turn up at my work, email or text 200 times a day.
I had no idea what was happening or why it had all started, it all came to a head when after a week of screaming/crying he admitted he wanted to kill himself, as he couldn?t get the intrusive thoughts and images out of his head. On the advice of NHS direct I took him to A&E, he came willingly as he had enough insight left to realise that he wasn?t being rational, he was diagnosed with Morbid Jealousy/Orthello Syndrome/delusional disorder, which they believe stemmed from depression, it took 6 months home visits, being off work, treatment and medication ? anti-psychotics and anti-depressants, a short spell in the mental health unit and CBT therapy to get him back on track.
It was sheer hell, my life was hell, he doesn?t actually remember any of last summer, but I do, I remember every second and every word spoken, I would say he is now 90% better, I would say I am 60% better, one comment leaning towards jealousy from him and it sends me in to a panic that its all going to start again, I?m hoping in time I will be able to relax a bit more, it is getting better. We have been warned it may return, but at least we?ll know what we are dealing with next time and it won?t spiral like it did, so recovery time will be quicker. People asked me why I was staying with him when he was treating me so awfully, but I knew he was ill and I couldn?t abandon him for being ill. Perhaps this is the difference from your situation, he had never behaved like that before and he knew it was wrong and wanted to get help, if he hadn?t then I may have walked away. This disorder is very serious and very dangerous for the partner ? you. I have never been able to work out when it can be classed as an illness or whether it is just that person?s personality, I imagine they are often mistakenly labelled both ways.
Could you print some information off about morbid jealousy for him to read, I did that and he recognised himself in it, which I think helped him accept it was a condition and needed treatment.
I kept a diary of last year, happy to share if it helps anyone, I felt so alone and desperately trawled the net for someone in a similar situation but found no one. I had never been close to anyone with MH problems before and didn?t know what the hell was going on or where to turn to for help. I learnt you have to fight for help though and that it isn?t available or offered easily. Our local MIND office provided the CBT as the NHS was at least a 6 month waiting list and RETHINK were a great support to me.
