*Disclaimer: I'm in no way a relationship expert. These are just things that have worked/are working for my own personal long-distance relationship, and I think they could help those also dealing with a significant other who may be a slight distance away. This will also be in 2 parts.
Being in a long distance relationship can be incredibly difficult. Things can get tense, arguments can ensue, and they can become much more intense, since you and your SO aren't face to face and therefore unable to read or understand body language. There are times where they may get on your nerves, but you still miss them everyday, and wish you lived closer so you could both fall asleep watching some movie on Netflix that you're both kinda into but would sleep through. I live about 3 hours from my girlfriend, which isn't the worst thing, but it does have its rough days. So here are a few things that I've learned that help make the distance seem not that far, and make the relationship wonderful for both of us.
HAND-WRITTEN LETTERS/CARE PACKAGES
We live in an age of fast communication. We can instant message our friends and loved ones within seconds, which, while it does have its benefits, makes us highly susceptible to overlooking the importance of conversation. I text my gf as much as I can, and I avoid double texting unless I'm correcting myself or it's important, as I know that she's still in classes and focusing on graduating. HOWEVER, if you want to truly make your SO feel special, take a little time out of your day to just write a quick or well thought out (depending on your timeframe) hand-written letter. Actually write down things, like what you'd like to plan for a future date activity, how happy your SO makes you feel, how you miss them, etc. It's ok if they come out a little sappy, just so long as your honest. Also, if you feel like making them EXTRA happy, include some snacks or cute things like stickers or jokes in a package and ship that to them. It'll make them smile, and it will keep them from getting hangry, which is probably the most important thing.
SHOW UP FOR IMPORTANT THINGS/PASSION WORKS
If your SO is involved in any kind of art or film or religious works (art shows, film festivals, concerts, church programs, etc), make the time to actually GO to these events. It shows you care, shows you're interested in their passions, and shows you love and encourage them to keep pursuing their passions. ALSO, if their parents are there, you get some bonus points. HOWEVER, this should work BOTH WAYS.
(I know this seems like a very short list, but part 2 will come out next week, and that will have the more emotional tips that you can do to help out your SO. Stay tuned!)
