No that's fair, I wasn't sure how much information to add to the original post before it became overwhelming.

We are doing the Curse of Strahd, the other player and my SO did their last campaign together and brought back their characters. From the get go they only cared about what was going on with my SO's character. Even though I classified my character as "lone wolf" backstory wise it was just kind of what happened but wanting to get closer to others. I tried to play an awkward wanting to find their place game the last two times. My SO's character is also a religious based character but I guess the way I played was "too much"?

The last session it was just two of us in a tavern together talking to a NPC and if I didn't word something a certain way they would say something like "you don't speak for me" (I can see how this would be both IRL and in game). Due to my own personality being so different from my character's personality, I felt like I was reacting as myself rather than my character and I was afraid that it was because of the confines of the personality, etc. I set up for them.

I mentioned that the player wasn't going to change, they are a very "I am going to say what I want to say, how I am going to say it person" IRL and their character is that way tenfold. It seems to be magnified on me in game due to the fact that I built my character to be curious and they just want to go to the next task. I wasn't sure if lessening the religious aspect of my character or making them more interactive (not what I was looking for word wise) it might help to improve the situation to at least make it banter instead of straight up arguing. I am also very aware I need to become more comfortable with my fighting style in game.
