Leave my relationship because husband can’t keep his eyes off of other women when we are out together?

My husband is perfect in every aspect except for his staring at other girls right in front of me. Not a glance where I can’t tell, full blown staring. It started when I was pregnant, now I’ve lost all the baby weight and make a huge effort to look great for him. Still nothing has changed. Can’t go out to the beach with him because he will literally move away from me to have a great view of another girls ass, can’t even drive with him in the car if there are decently attractive women outside, he stares. Y’all I have told him before how hurt I am because of these actions and he still does it. He gaslighted me for the longest time told me I was seeing things then finally admitted up and apologized. Now he’s back at it. My insecurity is crippling at this point when I’m out with him. It doesn’t really help that I know he’s not a fan of my new mom body even though I’ve worked my ass off to get in shape. I know he would like for me to get a breast augmentation since having our son and that hurts because he really loved my breasts before. Also can’t even afford a breast augmentation right now so I’m stuck feeling shitty about my breasts because of him. Basically he is a great father and great husband but his actions when we are out make me think I’m not enough, and make me feel insecure about how he acts when I’m not with him. Any experience on if you can trust a guy that is so obviously ogling other women to the point that they notice as well 🤦🏻‍♀️? Right in front of you..
