24F Just entered Long distance connection

I 24F met my LD connection 23M on FB dating. I wouldn’t say we’re quite in a official relationship but it seems to quickly heading that way❤️ he makes me feel so happy and valued as a person but this would be my first long distance relationship so I’m worried. We both have physical touch as long languages but he doesn’t seem worried about the distance. We live about 12 hours apart and I’m thinking of visiting him at the end of the summer. I think I’m just holding back because I’m nervous to go all in. Any tips, advice, stories?
