I need your help he said I want to get off of drugs-( my first husband) cult related

This was not long after we seperated, just a few months. I still loved him and wanted to help. I suggested he get involved with the church I was part of. 'they help people on drugs' I said. I don't know the whole of his story. But I do know that he was at first attached to the household in Milton keynes. At first they were very supportive loving and accepting. But he was struggling because they expected him to get clean just on the strength of their prayers and going from meeting to meeting at the same time. I know that some guys got clean because other than at night they would be either working or at a prayer meeting, it was constant. But he needed more support than that. At the same time the leader of the household was constantly nagging him and finally railroaded him into signing our divorce papers. If I had known this at the time I would have given him more time and put a hold on proceedings. Especially as I was unsure myself. He did eventually cave into the pressure to sign them. He later moved to another household in Northampton and then into his own place by this time he was baptised. At one point we got back together. However it was later revealed that he was continuing to use drugs secretly and we split up. (It was to be a further 16 years later that he got clean). He didn't stay involved with the cult long. But long enough to get his head messed with. Whilst in the Northampton house he was assigned a 'caring brother' they are someone who is assigned to look after you spiritually, friendship wise too. I had no idea but this was the guy who later became my second husband. He had learn't all about me and then made a move on me. My first husband still hates him and would like to get his hands on him to this day lol. This is all of the story that I know. But imagine my shock when years later he told me about this.
