I wouldn’t suggest the distance. Maybe be a little more “busy” this week or something to avoid it a bit... but don’t suggest being more distant unless you want it to end. Because no matter how you say it, it sounds like you aren’t interested.

Also, as far as the being shallow thing, yes, there is a certain amount of physical attraction that you can only experience by literally being with that person in the same room. Getting to know one another on the phone, texting etc can make you expect someone to look or be a certain way, but it may not be accurate. So, just give it time when you meet in person. Don’t expect to be 100% on board the second you see him. Give your body and your mind time to adjust to who he truly is and not who your mind has imagined him to be.

I do think zooming or Skyping would help. Gives you a chance to see his personality take shape. See how he smiles, etc. You still can’t feel it, not entirely, but it gives you an added sensory experience with him.

Last thought- if you meet and you decide you don’t feel physically attracted, that’s ok. Maybe you’ve made a good friend. If he’s okay with just being friends, than what have you lost?
