Thinking about it now, perhaps when DH is aggressive with me, it must trigger me and I go into scared/helpless child mode
Same here op , again, something worth exploring with a counseller. Do you find it hard to assert yourself in other situations with people similar to your H ?
Im not sure i would bother telling him his behaviour is unacceptable, he knows this , thats why he only does it in private. I had a lot of counselling about this and it was really usefull.
Re his aggresive behaviour ,I would get suckered in every time. He would be rude or aggresive and i would quite rightly object. He would then go off on a tangent, effectiveley purging himself of his emotional crap. Each time i would be left feeling ignored and angry.
I often thought he just didnt get it, but he did, all too well. In effect i was simply a usefull vessel for dumping his feelings into , and id unwittingly take them on. It might be usefull for you to veiw these incidants similar to a child attention seeking in order to have a row. You dont have to engage, defend yourself or try to explain that your upset, he knows all these things .
His angry feelings are his, not yours, refuse to take them off him anymore. Next time he is rude or whatever, simply remove yourself, go out, run a bath, just dont engage, same as you wouldnt with a stroppy child who accuses you of being tight cos he cant have 50 biscuits.You wouldnt take that on, dont take his crap on.
Dont try to get him to apologise or take responsibility, he wants to blame you, so what ? Let him. Your emotional reactions are his tools that he uses to manipulate you into becoming upset so he feels superior " Arent i clever, ive just really upset cherry ".
Are you able to tell when hes going to start this ? Theres often a cycle to this sort of thing. Is he gaslighting you, telling you what youve said, havent said, or denying hes said things ?
