What do you guys think of your girlfriends having a beta orbiter? What's your take on this?

I was looking through my gf's phone and a notification from a guy appeared, telling her "you're not the way you used to be, I don't get the same vibe from you anymore" or some shit like that.

I scrolled up a bit and about a month ago this dude was saying he's really hungry not knowing what to eat, and she sent him a mirror pic of her (fullly dressed, but pulling her pants a bit like making room towards her underwear) with an arrow pointing to her pussy, like telling him to eat her pussy.

Now this guy is a complete chimp... Calling him a beta would be a compliment to him. I know for sure she doesn't fuck him, 'cause he's fucking disgusting, both aestetically and mentally, you should see the way he talks to her.

I think she only uses him for some free weed and free stuff, after reading some more of their convo. Obviously I don't feel threatened by him but the simple fact that she talks to him and sends him that kind of a picture makes me uncomfortable.

What would you do if you were me? What would your advice be? Should I just let her get free shit from him while I'm fucking her or straight up soft next her? I appreciate it!
