"oh Well, Doesn't Matter"... (To You Maybe, But It Matters To Me)
I feel like she is saying that my thoughts are not important, that my concerns are trivial, that my observations are not interesting. She says it a lot, and it's getting quite irritating. I've noticed it can make conversations quite one-sided, because I get increasingly less comfortable with expressing my thoughts and feelings.
It cuts conversations short very quickly. It annoys me most when the matter is something that "matters".
I have a couple of options for dealing with it. One is to just spend less time with her. This is definitely an option, as I enjoy her company more when I don't spend too much time with her. Another option is to explain to her how it comes across. I think the best thing to do is tell her when she offends me, but I find this difficult to do.
Over the last year or so, I've come to tell her less and less about how I am feeling and what I think. I think it is good for me to develop my own independence of thought and confidence in my decision making. I think what I often need is a discussion, but what she wants to do is give me the conclusion and wrap it up. I'm a very different person, and I need to do things my way.
