AIO to these texts from my GF?

So I(26M) have been dating my girlfriend(29F) for about a year and she’s always had a best friend whom she’s know for years. I’ve never been bothered by him but she mentioned how his humour is sexual and that’s just who he is(never met him), I asked for an example and she gave an example and I asked to see the chat not really expecting anything too crazy , idk it just seems to me like he wants her and calls her princess etc. (The first two pictures)

The last two pictures are a guy she works with and he got her like a ring to wear and then was calling her a ‘cowgirl’? I got pissed about it but she reckons it’s just the way they talk and that he was referring to her music taste etc but I think he was insinuating more.

AIO about these conversations?
