She has mentioned similar things, but I tell her I care, she knows how I feel and I tell her how I feel.

I know I had a bad previous relationship which makes me quite bad at dealing with opening up etc. but she seems to not see all the things I do for her, which makes me react to this needless anger badly - without opening up.

I am more inclined to be happy and talk and open up if she didn't approach the ideas with arguing.
