How do I survive a secret romance if I only have contact through the Internet?

Use secure apps, such as the Line app. Using this, only you and the other person can view it unless someone else is standing over your shoulder or you willingly allow them access to your account. The only way to sign up is through your mobile number, and you have to confirm through your phone the first log in on a computer or other device. This allows you to know if someone is trying to log into your account. Another option is Snapchat. Snapchat allows you the option to save and unsave messages at any time. It's fast, easy, and super secretive.
