Focusing on Partner’s Flaws

Something I have noticed about my struggle with ROCD is that my brain tends to look for flaws in my girlfriend. One of the ways this comes out is when she has feelings or is upset about something that I don’t understand. For example, if she’s worried about something that I am not worried about my brain will tell me that she is wrong, annoying, etc. I love her and hate having feelings like this, which is why it is so frustrating. It also comes out when we have fights or arguments. My brain will start finding everything she’s doing “wrong” and it just makes me more mad. It’s like if she does something that outside of what I would do/feel it’s wrong to my OCD
