Other girls wont stop flirting with my boyfriend..?

So, he's a social guy, and I don't blame you for wanting a guy who only has eyes for you, I only have eyes for a girl too. Obviously, there is nothing you can do to stop this because as he said, he is still going to talk to his friends, which would include all the girls who have kissed him or like him, also dirty texting between friends is actually pretty common. The only thing you could do is tough though it, because there's nothing you can do to stop girls from talking to him, or him from receiving dirty texts
