I guess I feel a bit responsible as I've enabled him all this time by taking on too many things to avoid him being exposed to too many stressors etc.
Nah, don't take on responsibility for his being exposed to stressors. That's not how management of PTSD works. It's not managed by others removing stressors.
Try to not beat yourself up for the relationship working out this way. It's a tough situation and you are taking courageous steps in the right direction. You have a lot to be proud of regarding how you are making really tough choices.
I feel a bit bad that if I leave I'd be leaving him without some critical life skills, and I've looked at it the other way around to try to check if I've been too controlling there (like if it was the guy managing all the money and then leaving his partner with no financial skills etc.).
He's an adult. If he truly is unable to learn how to pay the bills on his own, or use others to help him learn, then he needs to be in a group home. I'm guessing that's not the case, and he's going to be able to figure this out - or he'll end up getting help he needs to do it. Try to let this go. Don't give him a plan. It's actually better for him to figure out what's going to work for him. You are not pulling the rug out. You are not forcing him to figure things out alone. You are letting an adult be an adult. That's all. It's very loving and respectful to let him figure things out for himself.
Thing is, the current reality isn't working for him either. He's outright saying it in so many ways. With you there right now, he can use you to avoid his stuff he needs to work on. Frankly, as weird as this might sound, it may be the very best thing you can do to help him to take a lot of space from him and stop helping him... if that makes any sesne.
Even if what he was saying were true, and I do ruin everything for him, aren't at all in tune with or connected to how he's feeling etc., just have a victim complex, then I would think the best course of action would still be the same thing... Spend some time apart and encourage him to get help for himself while I get help for myself.
Yep. You are spot on. And what he is saying isn't true! Again, this is hard stuff to walk through, and you are doing so much right.
I've emailed my therapist to see if she can see me this week. I am a bit uncertain of how to proceed.
This is awesome! I'd still work on the plan, and hopefully you can connect with her soon for extra support. Also, find any excuses to bring the sentimental stuff to your Dad's place.
I need to work out who I can try to stay with, and what to do with our pair of rabbits where one needs medication. I'll probably see if the SPCA might take them for a short time while I figure out what to do.
Sometimes there are folks that can be found to foster pets for someone getting out of an abusive relationship. Maybe connect with the local domestic violence shelter - even though he hasn't hit you, this is still abusive, and they may know of other options is SPCA doesn't know of any. Also, rabbits are not too cumbersome of pets and hopefully someone you would stay with wouldn't mind them staying too for a short bit. If anything comes up and you need to get out to stay safe and alive, sans rabbits, do it. They are better off with you safe and able to get them later than you being harmed.
But do I tell him? Do I tell him that I think his unmanaged PTSD is making it too difficult for us to sort out any issues we have and that I think he needs medical help, here are some numbers or I can help get him in touch with someone first, but I'm going to organise to go stay with a friend/my dad? Or do I just organise all of that first and then let him know essentially on the way out the door? I have a lot of my mum's stuff, sentimental things, stored here and I'm worried if I go he'll destroy anything I've left behind. I'll be devastated if that happens to the last of what's left of my mum, so I need to somehow take that somewhere. But he's always home, so it's not like I can pack a bunch of stuff up without him noticing.
If anybody has any advice on how to go about this please let me know... I'm going to talk to my therapist too if she's not too booked up.
Don't tell him right now. The day to explain may come, but not right now. It's ok to come up with a plan, get out, calling a suicide crisis line and asking them to check on him after you move out about the same time you explain why. If you are in the US, you can contact the United Way (211 from any US phone or online) and they may be able to connect you with a non-profit or other group that can help with a quick pack-up and move-out.
He's not stable enough right now to be able to handle the kind of conversation you want to have about his PTSD symptoms. I could only see it happening in any kind of helpful way with you at another place, and then he can't harm you or himself to try to stop you.
I'm making a list of things that I want to grab to make that a bit easier. I'm really anxious about talking to anybody but the more I think about it the less I want to keep doing this forever. I've thought about it and I think if he had any other kind of support network, friends family etc., I probably would have left a while ago. But I guess it's not my fault he has isolated himself from everyone for a long time (the family isn't his fault). I don't have a great support network either as I get pretty socially anxious, but I do have increasingly good friends from some of the activities I took up to try to improve that. I'm sure they would help if I can bring myself to ask them.
If he indicates he has plans to end his life, and certainly if he threatens to kill you again, drop everything and call 911 or the local suicide crisis line. There are text options as well, if you can't call. (Google for the best options in your area.) When someone is openly stating homicidal or suicidal threats in fits of anger/rage./panic, that's the time to get help. I've known too many people in my life who have said these things, no one called 911, and people died within hours. Don't ignore the statements or take them as anything less than legit. Your partner is unwell. The best thing you can do to help is back away and let professionals know what's up.
I'm so sorry you are going through this.
