Being far from each other means having to trust each other. If you start questioning or doubting, the relationship won't last long! Good communication between you is essential. Stay in touch, talk to each other at least once a day orally, by phone, or better, on Skype. Text yourself throughout the day, without overdoing it. Don't panic if your man doesn't respond for several hours:he may just have had a surprise meeting and no time to tell you. Communicating well allows you to keep a healthy relationship and also to be part of each other's lives on a daily basis. Talking to him every day will also allow you to resist the temptation, if you care about him and see that he cares about you, no need to ruin everything for an unimportant flirt. Going the distance isn't easy, but if your relationship is worth it, don't worry too much!
Knowing that the remote relationship won't last forever is essential. There must be a possibility of a future for two, to be able to find you in the long term. For this, one of you will have to make concessions or decide on a project that allows you to really have a life as a couple. It's up to you to see if he's the man of your life and that he deserves all these efforts or if this passing love affair will do you more harm than good. If you decide to stay together despite the distance, it is also important to be able to see each other as often as possible, and to enjoy each other! Enjoy every moment in his company and do activities together! Finding common passions will bring you closer and bind you even more, while waiting to find you for good for a life together!
