Me: F Early 20s Him: M Early 20s

We'll call my boyfriend "T".

T and I started dating exclusively about a month and a half ago, and things have been going swimmingly! The entire time we've been dating we've both been having tons of fun, everything is so positive and enjoyable, it's great. The sex is phenomenal, we have a lot of the same opinions and views, and not to mention we're able to keep each other intellectually stimulated as well. We've even met some of each others family. In short, this is serious long term relationship material.

The thing is, I'm leaving to go to England in about a week. It's a study abroad program that lasts for three weeks, and I've had it planned for about a year now. T and I have talked about it, considering it's happening so early on in our relationship, and we both agree that we want to keep our relationship exclusive and stay together. 

Granted, I'll only be gone for three weeks, which is a lot less than other couples have to deal with, but I've never tried anything "long-distance" before, and I'm not exactly sure how to keep this great relationship up and running while I'm a whole ocean away. (Ex. Should we talk every day? What, besides just talking, could I do to keep some flirtatiousness/ romance alive? Etc.) In addition, T is being extremely supportive of me, but I can tell that he feels a bit sad that I'll be going away. (I honestly feel a bit bad too, haha. I'm really going to miss him!) Is there any way I can reassure him that I'll still be coming home "to him"? I somewhat have a hard time talking about my feelings. I really want this whole thing to work out, he is absolutely amazing.
