How can my hubby even think of calling him his best friend, I can’t believe this, but my hubby trusted him.

Though he has been saying bad things about my hubby to me right from the day I knew him and my hubby ( Then fiancé), he said things to me not to trust in anybody in a relationship, I always wave it off cos I don’t allow gossip in my marriage. The cat was let out of the bag 3 days ago, I was off duty, I didn’t go to work, I just finished doing laundering when he knocked and came in, I also have a female visitor at home, both of them started gisting, I left them in the sitting room to my room, I was surprised when he came into my room, I was on the bed, he came and sat down, threw his hand on my waist, I stood up immediately, I couldn’t believe the scene, next he wanted to cross his two hands on my neck, I pushed him out and asked him what is this all about, then he opened his stinking mouth to tell me how he was attracted to me from day one, I and him should start a secret date without my hubby’s knowledge, that after all my hubby is cheating ( of which my hubby doesn’t), that he can take me to any hotel (As if that’s what a woman wants), that my hubby can’t take me out, infact a lot of rubbish he said just to get into my pant, SOME guys can be a dog in human form, I turned him down immediately.

Right now I don’t want him to near my house let alone being my hubby’s friend any longer, the issue now is that if my hubby happens to hear exactly what happened, he won’t take it easy with the guy because he’s a hot-tempered person, but how can I make my hubby understand that this guy is not a guy to keep as friend let alone close friend?

Even if my hubby is cheating, is that a justified reason why I should cheat?
