Forgive long post: I don't want to drip feed. Have NC as H could identify me from previous posts.
H and I unofficially separated a few years ago but have been living under same roof. Our relationship has been more or less amicable but there's no going back for either of us. He is a recovering addict and has been EA in the past. At his worst, he was very controlling and incredibly angry. He used to get cross if, for instance, I asked him to look after the dc while I went to the outhouse to put the laundry on - how mad is it that I had to ask? - and then would be cross later that he had no clean socks. That sounds so stupid, but every detail of my life was like that. He has also thrown away whole meals because they were 'disgusting', got cross with me when I woke up in front of telly and he was watching porn and I told him I didn't like it, held me accountable for everything that ever went wrong, seriously damaged the kitchen worktop with a carving knife. When the dc were tiny I wanted to leave because I didn't want them thinking it was ok to speak to a woman the way he spoke to me. This was all when he was at his worst.
He then entered a 12 step programme and his behaviour changed radically... He has been unrecognisable from the man I describe above: genuinely sharing responsibility for the dc and work around the house, trying to make amends for how he was in the past, etc. Everyone has commented on the difference. He has been 'clean' for a few years, but there were a few isolated crappy times when he has really let me down. The last time this happened I started making plans to leave but then he was admitted to hospital with major health issues (unrelated to his addiction and completely real and awful) and so I put my plans on hold. We've been together since university. 20 years. Half my life. Oh my God.
He wants us to continue to stay under the same roof because he was in the middle of a horrific divorce as a child and doesn't want our dc to have the same experience. We're currently renting, but he wants us to buy a house together to give the dc security. I agreed to this initially, but, sadly, I can see the signs of his addiction and controlling behaviour returning and I WILL NOT go back to walking on eggshells and I will not tie myself to him financially by getting a mortgage with him.
I'd love to have the dc with me all the time, but I realise that may not be possible.
I have some lovely friends in RL who being v supportive, but I turn to the good women of MN for advice on how to do separation well.
