Thanks for the replies. Seems like context is definitely needed...
Partner of three years, he had a v troubled (abusive) childhood until he left home at 18, when he then re-connected with loving family he'd been cut off from. Sadly within about 10 years both these family members died.
So he definitely (openly) has issues with abandonment/loved ones leaving. Also stemming from his childhood is a (completely understandable) fear of conflict or arguments.
He has not sought out any professional help or counselling to deal with the trauma of his childhood, but self-medicated with weed until very recently (decided to quit two weeks ago)
I find it difficult to navigate between wanting to be completely sensitive to how his childhood has affected him and reassure him of my love for him, my commitment to our relationship + life together... while also trying to deal with how his insecurities from trauma can affect both of us in daily life.
I find myself holding back or agonising over words to make sure I am only using positive language. But sometimes (like last night) I get frustrated about something - because I am human and we are both going through stressful times at the moment.
I was frustrated that his opinion over something we need to buy for the bathroom was changing every time it got brought up - I said that he never seemed to remember what we'd talked about before and that sometimes it made me feel like I was going insane when he says he never said something/we didn't have a conversation. He instantly got v defensive, said he didn't like being told he makes things up, asked if I actually thought he would try to lie or deceive me and said that if he's that difficult to deal with then he has no clue why I put up with him - and went to bed. It all felt like a massive overreaction to me, tbh...
The only explanation, to me, for him to say this is as Mousey765 says - a refusal to engage in difficult conversation. I don't think he is actively trying to manipulate me. But I do think that in itself the sentence is manipulative. The trouble I then have is that I completely understand why he is saying it - I understand that he is remembering the trauma, he wants to shut down and hide and he's worried that he is always going to be abandoned... But how can we let that rule the rest of our lives together? Am I not allowed to ever have a concern or a frustration - and if I am, I mustn't bring it up?!
Apologies for the essay!!! I hope it's not too rambling...
