Hearing the voice of someone you love can make a huge difference, especially if your partner's having a rough time.

Making a little digital home to the two of you can be a nice touch — and there a lots of apps for long-distance relationships that can help make you feel closer together.

When you do visit each other, make it count by leaving little surprises around their place for them to find after you leave. Maybe it's their favorite snack or little notes or pictures of the two of you — just hide a few little things to make them smile.

Fun fact: you can order delivery from anywhere you are. If you know your partner is at home having a kind of hum-drum day or going through a stressful time, their favorite pizza showing up at their door can totally make their day.

If your partner isn't the type to find pizza romantic (because they are wrong), then good old-fashioned flowers and chocolates can be a great treat. A little old-fashioned romance can go a long way when so much of your relationship happens through technology.

One of the hardest things about long-distance relationships is that they can feel interminable, so keep talking about the future and making plans. Even if you don't know exactly when you'll be in the same place, start talking about trips you'll take, how you want to decorate your apartment, or things you'll do once you're living in the same area. It may just be theoretical for now, but it can help you feel closer.

Social media shout outs can be a nice little surprise — just take it easy on the cringe factor if you know that it's not really their style.

The easiest way to make your partner less lonely? Make sure that they're not alone. Plan a visit to surprise them — and just hope they didn't plan to surprise you the same weekend or you could end up in opposite cities. But then you'll basically be in a rom com, so win-win.

Browsing for Airbnb options and booking flights can actually be a lot of fun, if it's something you're looking forward to. Send each other links and plan the vacation of your dreams — the buildup can be almost as satisfying as the trip itself.

It's amazing what you can organize from another city — or even another time zone. If you know your partner is really stressed, you can organize a cleaner, laundry service, or whatever else they might need. It will make their life easier and be a great reminder that someone's in their corner.

It's easy to get lazy in a long-distance relationship, but the more you share of your life then the closer the two of you will feel. Send little photos as you go about your day so they can feel closer to you.

Who says the love letter is dead? Some emo song lyrics and some snail mail combined will have you acting our your own little Elizabeth Bennett and Mr. Darcy moments.

You don't need to be in the same place for game night. Play a board game online together or use Facetime to play Battleship — that way you can get all of the competitiveness and fighting, wherever you are.

Go for a classic date night option with a bottle of wine and a move. Skype always works, but apps like Gaze let you watch movies together in real-time, no matter how far apart you are. Plus, you don't have to fight over popcorn.

When's the next time you see each other? Start a countdown. Send a daily update to your partner or mark it in your calendars and build the excitement as the day approaches. It gives you something to look forward to and can show your partner how much you can't wait to see them.

Rituals are important in a relationship and when you live in the same place you come up with them naturally. Maybe it's a silly dance you do while brushing your teeth or a routine you have for making breakfast together. When you live far apart, you can still have routines and rituals, you just have to be a little more creative. Maybe it's a quick good morning phone call or something you text every morning or every night or a silly inside joke — whatever works for you.

When you see your partner, give them a stack of little notes for emergencies, sealed in envelopes. When they're feeling stressed, blue, or really lonely, they'll have a little stash to go to for a pick me up. It's a thoughtful gesture and one that helps when they need it the most.

If you get the sense that your partner is struggling, try to get other people involved. You can team up with family or friends they have in the area to try to organize something nice for them — or even find out their schedule from a coworker so you can send their favorite lunch one day.

Often we miss our partner when we're going to sleep and we feel like we should be in the same bed. Try sending a blanket or a pillow — something cozy — that they can have near them at night.

When you're in a long-distance relationship, keeping things alive can feel like admin — so, every once in a while, just get really soppy. Call them out of the blue just to say I love you, send a cheesy text, or just a heart-eye emoji. Whatever your way of gushing is, make sure you keep it alive.

Being in a long-distance relationship isn't easy, but committing to making it work is key. Take the time to make your partner feel loved, supported, and make sure they know they're not alone — it's the best way to keep your relationship alive.
