Need some advice on relationship/moving.?

Hey, well i met this girl about two years ago, we have been really good friends we have helped each other through alot, deaths, etc, now we want to take it to the next level but the thing is we like over 400 miles apart, so we suggested semi moving intogether, by that i mean me moving down to where she lives and her staying there most nights but still lives at home, so we can build a better relationship and become closer etc, now i think this is a good idea, but im just not 100% sure, she says she loves me and she does show it etc, but i just have some douts, me moving away from home to somewhere i dont know is a big thing for me, i do wanna move because i also love her, but man im terrible with girls i like i always seem to say stuff and it ends up ruining it, i just dont wanna mess this up with her because i see a real future with her, she is so pretty and im not lol, so i cant see passed a pretty girl liking a ugly guy.. can someone give me advice to get me into shape coz im sinkingNeed some advice on relationship/moving.?
BELIEVE ME THE LOOKS ARE IMPORTANT FOR YOUR FIRST METING THAN THE GIRLS LOVES YOUR CARACTER AND FORGETS ABOUT YOUR LOOKS THEY NEED A MAN TO SUPPORT THEM SO OF COURSE YOU SHOULD MOVE IF YOU REALLY CARE AND THEN YOU WILL DISCOVER IF SHE IS REALLY YOUR DREAM GIRL AND THE SAME THING FOR HER A BIT OF SACRIFICE WILL MAKE HER FEEL IMPORTANT AND SPECIAL TO YOU GO FOR ! AND DON'T HESITATENeed some advice on relationship/moving.?
Your doubts (the relationship being ruined, and moving somewhere you are unfamiliar with) should be enough for you to tell this girl, you would rather wait. How you look should not matter. If she is already saying that she loves you, you should feel confident that no distance will change her feelings. Why cant she move in with you or closer to you? Or better yet, why not meet each other halfway (both of you move 200 miles away) If your heart really isnt in it..follow your first mind, otherwise you will regret it.
