Make a film and say it.

First, you are both too idle, so you have a lot of time to concentrate on surfing the Internet and even observe every detail of each other's cyberspace. If you all apply this detail to business, you will gain a lot.

Second, the details you observe are different. Your attention to his every move towards you shows that you are too strict with him. And he was worried that your traces in his space might cause him trouble, so he deleted your traces. As for how to explain these behaviors, concrete analysis is needed.

If you two don't make it public to both families, then his behavior is easy to understand; If it is made public, his family may be dissatisfied with some of your performances; If he is not afraid of being seen by his family, it is a bit serious. Maybe there's someone else.
