Advice please

So, I’ve noticed that every time my guy sees a woman on the tv who he thinks is attractive, he always says “d*** she’s so f-ing hot” or something along those lines and sometimes it gets under my skin. I never say anything to him because I feel that is my own insecurity and I should work on that and not take it out on him.

I was in a very abusive relationship before him and I’m still working on my insecurities, like this one in particular. I’ve come a very long way with rerouting my thinking so far but this one just sticks. My ex used to intentionally make me feel bad and compared me to other women. I know that isn’t the intent of what my boyfriend is doing but I can’t help but to feel hurt.

How do I get past this and heal so my insecurities don’t become an issue in this relationship?
