Hey OP.
Yes, I can. Your relationship sounds exactly like the last relationship I was in. I left a year ago.
Really good news that you realise what is happening to you here, and that he is being abusive and manipulative. It takes a lot to actually come to your senses and realise this stuff, but you are there and that is great news.
It took me quite a while to mentally recover from what happened to me in my relationship, and I did a lot of learning about abuse and in particular, narcissistic abuse, which is, in my opinion what you are describing.
The tactics he's using are known as DARVO. Deny attack, then reverse victim and offender. It is a commonly used tactic of abusers to turn the tables on you and make you the problem, you then end up defending yourself rather than addressing the original complaint and they therefore get away with whatever it is that you were trying to talk to them about.
You will likely be minimised and dismissed on the regular, you will probably feel like a complete shell of a person who can't make basic decisions about anything anymore. This is how the situation affected me for sure.
I would get so angry with the arguments that I would react, and then it would become my fault for being "crazy" and I would be told that I was mentally unstable and to get help. I actually did end up on medication and also seeing a counsellor. I went to couples therapy with him and was a jibbering wreck while he played the concerned partner, further cementing the idea that I was at fault. It was extremely clever on his part.
Lundy Bancroft has written a great book called "why does he do that?" which would be useful for you to read through and highlight areas that you think apply to you, or strike a chord with you. Flicking back over those highlighted areas can often bring home the extent of what you're dealing with.
Another great resource is Dr Ramani on Youtube. She talks extensively about narcissism, and the effects it has on survivors which can be extremely severe, cause sickness, mental health problems and extreme trauma in some cases.
I think that in your case, you need some outside support and people you can trust to help you to figure out a way of unsticking yourself from this situation. It may take time.
As much as I know how infuriating the DARVO tactics are, my advice (that I wish I'd known about and had the strength to take) is to stop arguing.
The bottom line with these people is that they are rigid, they don't change. Nothing changes them. Nothing you will say will move them to see your point of view, show compassion, show empathy, show kindness - it's not who they are. You have to reach the point where you accept this fully and wholeheartedly and rather than being affected by the cruelty and the outrage at them doing this to you, you simply realise that you are dealing with a completely different beast to most normal human beings. I am probably making this sound dramatic but my genuine experience is that these people are malevolent, damaged, lack empathy and will not be made to see any other way. I therefore do not consider it "too dramatic" when you are going through it.
Grey Rock is another tactic that you can use, so it is that you don't engage, you don't argue, you just nod and act like a rock. You don't give them the reaction they are seeking. Be careful with this because it can cause them to become more angry (that's what happened to me) as they attempt to get a reaction from you. Do not go too far with this if it is going to put you in physical danger.
In your situation I would resolve myself to agree, reduce conflict by agreeing, nodding, smiling and not trying to argue back. I'm not saying that because i want you to accept the situation, i am saying it because it will take the pressure off you by making you a "boring" target while you get your ducks in a row and figure out a way to escape.
You do need to leave this situation darling. You need to get some support and get out. I understand the financial situation, but have a think about what you can do to extracate yourself. Speak to Refuge, see if you can get legal aid and see what you can do to start putting a plan together.
You are not on your own in this, I just want you to know that, there are so many people who are in the situation you are in and I know how utterly miserable and soul destroying it is. I am sorry for writing the long essay on this.
I used to go to sleep at night and hope that I didn't wake up, it became that bad for me. Now that I am out and a year later, life is better, it can get better, in your case it may just take some QUIET planning. No threats to him, no "I will leave you" or any of that - do it quietly.
I am sorry that you are in this situation, there is light at the end of the tunnel for you though, there really is.
