It is not an ideal situation to be far from the person you love, whether you're two hours or twenty-two hours away.
I know people that dated for years in high school and broke up as soon as they got to college, because they didn't want to try the distance. However, we did. It was incredibly hard to go from walking through the halls of our high school together and hanging out every day after school to having basically two separate lives.
As cliche as it may seem, there are days when I miss him so much that it physically pains me. My heart hurts. I am experiencing all of these new things in this brand new place. So, it feels like he should be here with me. For us, the concept of "out of sight, out of mind" doesn't ever occur, because we are always thinking of each other and talking.
Communication is so important in a long distance relationship. When you're close, talking every second of the day seems like a lot. But when you're far apart, knowing where your person is during the day can make you feel a lot more comfortable. Being able to trust the other person is key, because if you can't, the relationship will never work.
Sometimes fighting can escalate when you're miles apart. There's so many emotions between both of you, and all you want to do is see them. When you have those fights, try to call them. Just hearing their voice can make everything better.
I am no expert, and I am still dealing with this too. When you find someone that you want to spend the rest of your life with, you will do whatever you can to make that happen. Long distance is hard, but with the right person, it'll be worth it.
