Advice please

So my husband isnt cheating but we been having this conversation literally like 5 fucking times that it's not okay for him to go talking to his friends about another females looks because that's disrespectful af when u in a relationship. Especially when you married, fucking act married. I'm tired of having this conversation, I know hes not cheating but hes lost my trust.

Here's the girl btw

His excuse is always, "oh its bro talk. That's all guys talk about, games females and cars. " and I been telling him a million times yeah i get that but you married. It's different if his friends be the ones coming up to him saying oh this girl fine af, then you could say something like ight go get it my boy, not DAYYYUMM u right or especially YOUUU the one fucking initiating that shit. He doesnt fucking get it.

It doesnt help that hes sexy af so he got hella thots in his dms especially since hes in the military. I'm just having this constant problem of him fucking disrespecting our marriage and I dont know what to do. What would you do in my situation?
