Playing victim?

Jane
So about a month ago my SO and I got into an arguement.. I could tell something was wrong so I asked and he began to tell me about how I sounded unhappy here (we moved in December to a new town) and about how I talked negative so often...he started to feel like there was nothing he could do. In my eyes, I saw nothing wrong with how I was acting, but I DID change all my thoughts to positive ones and the next week was way better. Well nowt there's another issue.. we got into an argument last night and my SO told me that he felt like he was "constantly walking on eggshells" because he feels the need to apologize a lot lately over things like I seem to be playing the "victim." I am now starting to feel pretty hopeless... I try so hard.. and I never even seen this as a problem before.. I feel like I don't even see there's a problem until he tells me because he is mad.. and I'm starting to feel like I'm just not good enough :/ what do I do to fix this?
