My boyfriend told me that I could eat with the opposite sex, watch movies, get in touch with some boys and maybe meet someone better than him. Why did he say that? Is it normal to say that?

It's rare to say that. Generally, if that man really likes you, you shouldn't be allowed to contact the opposite sex often.

When he said this, he was either joking to see if you would dump a boy who is better than him in the future, or he might have a mistress or like you very much, and advised you to give him up if you meet someone better. .

If he is a joker, it may be a joke. If he is not a joker, he may have some private affairs.
