Help I’m too nervous for no reason

Okay, so I really don’t know how to keep this short so this might be longer than it should be but here goes, so I’ve had a friend for a couple of years now And he is just incredible He’s funny, kind, smart and overall just amazing and a few days ago he asked me to be his boyfriend which despite never saying it out loud I accepted and we have even told a mutual friend, we are dating and we are going out this week to kind of test the waters and see how everything goes and I love him and I know he loves me but I’m still nervous. I’m going to fumble the bag and he’s going to say he can’t do this. Is there any advice y’all can give me? I kinda need it. 😅
