Is it appropriate to call and text her after breaking up?

It depends on which one of you breaks up first! Is it that the relationship is not peaceful, the family is opposed to being forced to break up, or he (she) betrayed each other! If you feel something is wrong, send a text message and make a phone call. This is a greeting between friends. As a friend, you don't have sex, your family opposes breaking up, and you send text messages by phone, which proves that you can't let go. If you betray a breakup, then the type of phone message may only be hatred!
