Yes we did, at first we tried the you can have sex but no emotional connections route. He was not keen on this as he needed an emotional connection to feel comfortable. He backed off and just went to professional services. When he was feeling the waters of another actual relationship he was telling me way too much and I asked him to just tell me the bare minimum. He heard this as me not wanting to hear anything and was pretty upset so he didn't tell me any information for a while. At the moment I am at the point that I honestly don't mind if he wants or needs a haram, I just don't need all the details and don't want to be part of it. What he actually has is a professional who is 'tutoring' him and he is not sure what he is going to do after this but is pretty sure it is not monogamous. There may be a few details missed but this is the gist of it.
My god, he's really done a number on you. He's totally totally gaslighting you. First prostitutes, then casual sex, now relationships (because he needs). I'm so sorry for you. I wish you had some real female friends in real life you could talk to about this, because I doubt anyone who cared about you would think this is OK.
This is emotionally abusive. It means he gets all his home comforts, and gets to keep his money, while you are left, sounding like a husk of yourself.
All the while telling you it's your fault and that you are the emotionally abusive one.
Have you heard of DARVO? Basically, when a bully reverses the blame so as to to accuse his victim of actually being the bully.
Deny, Attack, Reverse Victim and Offender
He's showing you what he is. He's converted what he wants into what he needs. It's bullshit.
