my best freinds bf crushing on me

So my bff bf is my freind but lately he’s been ringing me everyday not bothering to ring his sister like he normally does it seems he’d rather spend his credit on me he always tell me how nice i am and that his gf tried to poison me against him and he says he’s always liked me Idk if he ment in a freindly way or he means he has a crush on me he uses phrases such as telling me I’m good stuff and everything about me is mad but he’s always liked me he says he wants to name his future baby after me and he always knew I was a good lass and that we got along more than him and his gf he also tells his sister how nice I am and how his gf tried to poison me against him. To I need to know if he fancys me because if he does I need to cut him off
