Most Helpful Guy
Unless he is still in high school, he needs stand up for himself more. He also needs to buy his own phone with his own money and pay his own phone bill, so that she cannot take it away.

I just read in a comment that you say he's 17 years old. It's wise to just end it. if he can lie to his mom, he'll lie to anybody. Including you. Trust me, I had this happened to me before indirectly by a close friend because she was doing things she wasn't supposed to do with her boyfriend. It was a toxic relationship to begin with and it caused problems for everybody around her. She lied to her mom and her dad at one point too. Or at least tried to most of the time. You're doing right by taking this step. My advice is to just drop the relationship. He has a lot of issues as is. Don't take on more than you can handle. I doubt his mother is paranoid. I believe it's because she knows him better than you do. And he's a liar. She doesn't want him having premarital sex with you that is very clear and I agree with her on that. Again, I believe that she can't trust him. Not because of you exactly.
