Does anyone get exhausted trying to talk to their introverted partner?

My partner is a deeply pensive, curious, beautiful intellectual person. But often retreats into his own world, and I feel exhausted having to make all the effort in communication.

He's socially awkward—sometimes charming and helpful, but often rude or condescending. As a result, most of my friends and family think he doesn’t want to engage. He rarely asks questions or shares much about himself, often responding with short, unengaged answers. This leaves me overcompensating in conversations, especially around others, and it feels draining. When we're alone, I feel like I’m constantly trying to pull conversation out of him. Despite telling him how I feel and even trying relationship tools, I’m starting to feel bitter and resentful.

I’ve realized that while his behavior was easier to accept before we lived together, it’s become much harder now. I realize that when we first met, I loved that he was up for anything and open for trying all the new things I wanted to do and all my crazy ideas. He used to say that I was so full of life and he loved that.

Compounded by the fact that he’s recently found out his job of 6 years may be phasing him out and he’s not been able to get any other offers. I know he’s feeling anxious, stressed, and inadequate.

For example yesterday his friend was visiting and left and I overheard him saying ok I’ll see you Tuesday. I had to ask him is he staying with us Tuesday? And how long, etc. (my wfh office is the guest room). He claims he’s told me this ( def didn’t. I would have written it down and made arrangements to work elsewhere). So I was annoyed at the lack of communication and what if I hadn’t overheard the convo he wasn’t going to tell me. I get over it. We make plans to go skating. He’s non communicative on the drive. He’s laughing at reading things on his phone I ask if there’s anything he’d like to share or talk about that he read on his phone. He says I don’t think you want to talk about motorcycles. I then just shut down and have nothing to say. 16 m later he says I can give you the same criticism. I said criticism? I just want to talk to you and spend time with you and I’d be happy to talk about motorcycles. He then just starts driving in circles and says where is the place ? I said um the roller skating rink? He says no the bbq place (we just had eaten lunch). I said are you still hungry? He says no I just want to go look at it. I said you could have communicated to me that we were going to drive somewhere else before we went skating. He then just scoffed in annoyance and I again had no desire to start further conversation or really talk to him the rest of the day.

TLDR: I’m looking for advice on how to accept him as he is without getting upset or bitter, and how to improve communication in a way that doesn’t leave me feeling exhausted. How to respond with more love, patience, and understanding and not retreat into my own non communicative world
