Ex-P and I have recently separated, mainly due to his infidelity: I have discovered him on sex sites (Adultwork, Collar Space, Craigslist, swinging forums) trying to arrange meet-ups several times throughout our relationship and forgiven him when he begged and cried for another chance. The most recent discovery was the final straw and I said we were finished. I have always found him out due to my spidey senses tingling prompting me to check his iPad history, which has then led me to all the websites he's been using and his profiles and messages.
We still have to live together as we co-own our house. He has refused to buy me out; refused to talk sensibly about me buying him out; will not cooperate with arrange sale. Recently, he has become incredibly aggressive - shouting and swearing at me if I ask him if we can discuss he house; texts and emails saying he hates and despises me and is going to make the whole process as difficult for me as he can, that I can't afford to mess with him or make him angry.
He has entirely re-written the circumstances of our break-up - now insists that I knew all about him using the sites and agreed to it; that I am lying in saying that it was behind my back; claiming that he only used the sites sometimes to catch me out and see if I was still snooping on him and would never have gone through with actually meeting up; and is generally constructing an argument where he is the poor victim of my despicable behaviour in snooping on him, which he is declaring . Whilst we did consider experimenting with polyamory in the early stages of our relationship, I later changed my mind and we agreed to be monogamous - largely because the activities we initially discussed such as swinging clubs and finding another couple to have fun with quickly gave way to him wanting to try far more hardcore stuff that I didn't want to be involved with. However, he spent a lot of time trying to "encourage" me to change my mind again and go ahead with it, including saying he'd leave if I didn't let him see other women or promising that he'd marry me if I went dogging, let him arrange gangbangs for me, or let him keep a sex slave in the house. (Just reading back this stuff makes me feel queasy.)
I'm actually becoming quite scared of him. He has always been verbally abusive and controlling, scary in itself, but it's now almost as if he genuinely believes he has done nothing wrong and that I am the bitch to be hated and despised for checking up on his online activity. I accept what I did was wrong but needed to know if he was up to no good again. I have been proven correct every single time I have checked up. This weekend he has been demanding I send him selfies to prove where I am as he doesn't believe I was stuck here unable to get home due to transport issues.
If I asked the police to log the situation now just in case it escalated, would they take me seriously? There's been no violence as such and the things he's said aren't necessarily criminal. If I explained that he is starting to appear unstable because of the aggression, what he insists the situation is and the way he would rather text for hours about all my failings in our relationship and how I was a let own as he only ever wanted me for kinky sex than sit down like adults and discuss our house and finances, would they just record it in case he kicked off in the future?
I just want to move on. He seems just to want to extend our misery and hurt me.
