My husband looks at other women

My husband loves me but he has a habit of looking at other women. To be specific pretty, blond, young, very slim women. He is attracted to that type of woman and it makes me feel insecure and angry.
I am a 45 years old mixed race woman so I look completely different…
Should I just tolerate it – that’s just who he is – and clean out my thoughts
or have a conversation with him. I tried before but he kind of denied the facts.
