LOSE HIM OR FRIENDZONE him ?

Amy
So I've been talking to this amazing guy lately. We open up to each other easily and we are just perfect for each other. However, he mentioned that he was previously a f boy and a pure asshole however, after he met me he told me he was open to change and I suggested things and he did as told! He signed up to the gym and eats healthy now. However he called me babe last night and I texted him saying , call me by my name lol. He said "you're the closest thing I have to bae" I said "your my biggest fear and that's loosing you." He was shocked but told me if I was smart as he thought I was I wouldn't loose him at all. TBH guys , I really like him. He's amazing and I do know that I have the capability to change him for the better. BUT I don't want to loose him. IF we date I'm afraid of him closing up and focusing more on the sex and not the bond. I really don't wanna loose him but I feel that EITHER way I will. What should I do??
