Always having to confess my love to him

Ok so I'm obv. In a relationship with my boyfriend & I love him very much I do, I tell him all the time! Buts it is ALWAYS that he wants me to confess my love towards him! He always says that I don't love him, he's scared to believe me & scare that I'll leave him and so forth but I'm tired of constantly having to get it through his thick skull of his that I fucking love him and im not going anywhere!!!!!! He's always questioning my love and Idek what to do because I'm tired of trying to prove my love to him if he'll just never believe me!
