He's called me 'hypersensitive' a couple of times and has also told me that when my partner is angry I need to go towards him to soften him as my partner has abandonment issues...
What you are reporting about your couples counsellor is extremely concerning. No counsellor can ever call their client 'hypersensitive', even if they think they really are!! He's gaslighting you! He doesn't know what happened, he has your version and your partner's version - for all he knows it could be much worse than either of you are reporting. So he can NEVER say you are 'hypersensitive'. It's not his place to tell you what you are or are not. He's just there to help the two of you process your thoughts and feelings and teach better communication.
I completely disagree about you having to go to your partner when he is angry in order to 'soften' him because he has 'abandonment' issues. When your partner is angry, he needs to take himself off to a quiet space and calm down so that he is not tempted to show you his anger. It is not YOUR job to manage his emotions and help him out of his emotions. That is your partner's work alone. And anyway, anger is a secondary emotion. So really your partner needs independent therapy to work through what his underlying emotions are. And that is NOT your work.
Then you say your couples counsellor wrote a paper: "The paper questions some of the feminist views on domestic violence and also explains violent behavior as a relational pattern rather than simply an individual choice."
OMG - really the papers that need to be written on domestic violence are : how do we stop women being killed at the hands of their partners .... not investigating feminist views on domestic violence. Violent behaviour is all about control. I would stop seeing him if I were you. In fact, I would report him somewhere.
