OP I feel for you. I have an ex partner who was like this: perceived everything as a criticism, stonewalled me (for hours, days or weeks), couldn’t discuss anything, wouldn’t ever see my point of view or show he cared about how I felt. Nothing ever got resolved, and I didn’t feel loved or respected.
I tied myself in knots for years trying to adapt to him, make allowances for him. We went to therapy. I talked to his friends and parents to try to better understand how he communicated and how I could help. I read books on avoidant attachment styles, and healthy relationships and tried to put it into practice.
He never changed, and the more I accommodated him the worse it got.
Eventually I reasoned that (a) he couldn’t help it / didn’t see what he was doing, or (b) he knew what he was doing, which was worse because it was intentional. Either way, nothing could change.
I eventually left him, saying the relationship was damaged beyond repair, and I wasn’t going to explain to him any further because I’d tried for years to make him understand and it hadn’t worked.
At that point, he suddenly became communicative, understood everything I was saying and claimed to be willing to change. It was too late, and the final nail in the coffin, because he essentially admitted that all along his behaviour had been intentional - a form of control.
I’m not saying your partner is the same, but I read a lot about these kinds of men on MN. I wish someone had told me straight before I wasted years on someone who (I now realise) was so deeply unhappy and insecure that they couldn’t do otherwise than undermine me.
I’m now I’m a happy relationship with a man who genuinely likes me, and it’s everything I knew it should be.
It certainly shouldn’t be as hard as you’re finding it. You deserve ordinary, decent communication. You deserve to be prioritised and loved.
I can sense in some of your replies that you’re becoming defensive and rattled. (Understandably, because some replies have been very unhelpful and accusatory.) But I got like this too - don’t underestimate how much his behaviour can change you for the worse, as you have to constantly stand up for yourself and beg for scraps of decency. I wouldn’t want to go through that again. I hope you get out.
