Accidental pregnancy/Catholic

Hey ladies! I found out I am pregnant. The guy I'm with and myself are Catholic, so an abortion is definitely out of the question. I'm obvs keeping the baby, but I am so scared to tell him. How can I tell him gently without it causing too much harm to our relationship? He's so sweet and I don't expect him to do anything but be accepting, I just feel like I'm going to be delivering news that will ruin his future. He's in college to become a music director and I feel like I've ruined that! 😭
