Need Bf advice

Lanisha • Instagram Lanispamshae I've been through a lot to say I'm so young.. Wanna know anything else just ask.
So me and my bf have been together for 8 months and we are sexually involved, we agreed on that we wouldn't talk to the opposite gender we both had slips ups..  as I'm going to bed I get a call from a friend that she thinks my bf is texting her he even goes as far as saying he is single and would love to take her virginity.. what should I do I've done my wrongs in the past and I really thought he was the one. How should I approach him?
