Long distance is hard, sometimes it can be quite unpleasant, but it's always worth it. Being away from the one you care about so much can be incredibly difficult. There are parts of your life you want to share with them, you want them to be there with you to experience and go through life together, but at this point in your life it just isn't possible. For now phone calls and video-call dates will have to do until you're able to get those moments together when you can spend time in person. Those cherished moments.
It's having to say goodbye repeatedly that is the hardest for me, that's something that doesn't seem to stop hurting, something I cant seem to get used to. Any visit seems to go by far too fast, so you have to try to soak it up before another farewell. It's also more unpleasant to solve disagreements, you'd rather see that person face to face and discuss it rather than resolving the issue from miles apart. Unfortunately even phone and video-calls don't always go so well. Dropped calls and bad connections make the communications more difficult, and can sometimes be rather frustrating when you just want to talk to each other. You also might think you'll get to talk to them everyday, but that doesn't always happen for everyone some have to go a week or so without communicating to their significant other. One of the other more difficult things to bear is seeing other couples together, you see how happy they are and just wish you could just have your boyfriend/girlfriend with you right then.
Despite that longing that doesn't seem to go away and the difficulties that come along with being apart, these are the things that make reunions so much more wonderful. A popular phrase in these situations is "Distance makes the heart grow fonder"- unknown. The distance and time apart can make the relationship stronger and more equipped to handle the times when you have to be apart. You have to learn to trust the person on a deeper level and as a result the relationship grows. Any relationship is work but this particular kind of relationship is unique and definitely requires dedication and patience in many ways. Have patience, talk when you can, resolve those problems (even though you might rather do that in person), and most of all remember that it's worth it for those moments together.
1 Corinthians 13: 4-7 - Love is patient and kind; love does not envy or boast; it is not arrogant or rude. It does not insist on its own way; it is not irritable or resentful; it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things.
