I know I don't know what to do
My girlfriend just moved in with me. There is one thing about her that I find very unattractive and before living with her I had enough space to take a breather when it started to get to me. Now I'm afraid that I'm going to say something terrible out of frustration but I'm not sure how to avoid this or say something to her that is constructive and not just damaging.
So here's the deal. She has a tendency to point out when she is right and to point out when others are wrong. Such as saying "I told you so", "I can't believe you did that/didn't know that" and there is very little that she doesn't "already know" plus other quirks like this. I'm pretty sure she is just insecure about herself and has created these habits as a defense mechanism.
The part that gets to me the most is that I used to be quite the "know it all" when I was younger and I try my best to be humble now. I try very hard to give others the benefit of the doubt and even admit to possibly being wrong when I feel I'm right. Not only is it starting to hurt and make me feel unloved because everything comes down to how right she is/wrong I am but I'm getting frustrated and find myself arguing with her over stupid things and having to just walk away at times. Not to mention my lack of desire to be affectionate.
Any advice on what I could say or do to break down this wall?
