How do I tell my bf I love him

I’ve been in a relationship with my bf for 8 months now we dated for 3 months then made it official so I’ve known him for a total of 11 months. Everything has been near perfect! He makes me happy like no one has ever made me happy! Before this relationship I was in an unhealthy toxic relationship for 5 years. I thought I would never be treated right or that no one would want me . This man has helped me through my ptsd he has helped me through my depression and anxiety. He’s seen me and stayed with me through my bad days. I’m in love with this man I love him but how do I tell him I love him? I’m soo scared to make that move and to scare him away. He hasn’t told me he loves me but I feel that towards him should I wait for him to tell me or should I just tell him?
