Help Please

So my boyfriend of a year and some months now are happy with each other. Our love and passion is still there. He tells me he loves me everyday, but I’m very insecure and he know that. And he does everything in his power to make me trust him and I do. I just don’t trust those girls out there. My boyfriend and I aren’t having sex until we’re married. However, I have a feeling like he does want to have sex. And there’s this girl that I know should give it to him. I just don’t trust her. Should I tell him to not talk to her anymore? Or should I forget about it?
