I have to say the most important thing in a relationship is communication as well as planning

Especially with in a long distance relationship you have to have a plan and respect eachothers wishes

It is also important that you take time away from eachother to much time together can be tiring and conversations with your parnether can be short so take time away form eachother

Also if something happens technology wise you have to have a back up plan when you need to be in contact with one another

And last but not least not to be selfish your partner has a life outside of technology and they may be going through somethings so it may be best to give them some space
