Why do men ask what's wrong just to argue?

A lot of things have changed between me and my boyfriend but during our last big fight it's like he has finally gone back to the man I love and giving me what I feel I had been begging for. Yesterday we got into it because he admitted during a discussion he adds females that he finds sexy to social media so he can look at them later. This makes me very uncomfortable because I've been cheated on by others before. I thought he understood before how I feel about liking thirst traps but now knowing he still doesn't mind doing that or even adding them really bothers me. I'm visibly still upset and he saw I was crying so he asked and I told him no I'm fine because it's always a argument. Why ask if you won't care?
