If you found a guy over social media and then got involved with each other or developed mutual feelings for each other, but then the guy doesn't want to show his face, what would you think of it? My girlfriend likes to chat with other guys on WhatsApp, Facebook, and other social media sites, but she hides it. We always fight with each other regarding this issue. What should I do? Will she cheat me someday (we have both promised to marry each other)?
