Man. some good and IMO harsh comments here.
Now, I have been married for 10 years, been with/dating my wife for 7 years before that (since High school). I am into Bass fishing i mean REALLY into it, she hates it. I am into firearms, she does not hate them but does not share my enthusiasm. She loves arts and crafts, I am not too crafty here. She also have a penchant for movies that make me want to lay down under a bus.
We work because we meet midway. She got a CCW, not because she really wanted one but because it was important to me that she be able to protect herself. I got a bass boat and she supported me in that large purchase because she knew fishing was something I really enjoyed. She knows she is number 1 and does not feel threatened by my hobbies.
As a younger man, sometimes I was a total nimrod in how I talked to her. In particular when it came to firearms, and my choice to concealed carry. I really had to sort of step back and realize it was me, not her that caused the reactions I got from her. My tone (not screaming but not understanding either), the poor choice of words (not cussing or vulgar but not the best), all came together to get what, at the time, I considered irrational reactions from her. I have had some time to learn her and her me and it has paid off a ton in our lives.
I bring this up only because we are really getting 1 side of the story, OP, you really are the only one who knows it or not but the next discussion you have around this, really take a long hard look at how you talk, tone, choice of words, etc and try to see if maybe there is something in the delivery of your point of view that may be helping to cause this. Keep in mind it may also be an expression on your face.
That being said, before I met my wife, I also dated a girl who was bi-polar and let's just say THOSE discussions were real fun. it made no difference what I said, what I did, how I said it, nothing would have ever worked.
