they had sex!!!!
The script does not specify. Use your imagination. They slept together all night.
Romeo shows up at the friar's doorstep in the early morning. He has not slept all night. He's been with a girl. The last girl the friar heard about Romeo liking was Rosaline, only the day before. All of a sudden, Romeo's talking about this Juliet--and he wants to marry her? I guess the friar's surprised.
Clearly you are talking about the Friar's plan which he had before Romeo was banished, not the one which he formed and gave to Juliet after Romeo's banishment. This plan was that the marriage of Romeo and Juliet would end the feud. In order for it to work, the families needed to be told about the marriage, and the marriage had to be made irrevocable by being consummated (until the married couple had slept together, the marriage could be annulled at the insistence of the parents). Romeo ended up being banished before either of those things could happen. In addition, the fact that he had killed Mrs. Capulet's favourite nephew meant that she hated Romeo completely and, as we find out, she is prepared to take out a contract to have him murdered. If that happened, the feud would not end, but would become more violent than it ever was.
It is so difficult to say what might have happened if Romeo and Juliet had been more open about the state of their affections. If they had disclosed them up front right after the balcony scene, their parents might simply have forbidden them to see each other, which might have led to their suicides anyway. Had they disclosed the fact that they were married before they had slept together, their parents would have arranged for their marriage to have been annulled and have forbidden them to see each other, with the same result. Once the marriage was consummated, there was no divorcing them (given Catholic policy then) but unfortunately by that time Romeo was an outlaw banished from Verona, who could not come in to Verona. Had the marriage been disclosed at that point, they would not have been able to live together, and Mrs. Capulet, already mad enough at Romeo for killing Tybalt, would have certainly carried through with her plan to poison him. So they would end up dead anyway. In other words, being less secretive might not have made any difference. Once you know that both Romeo and Juliet would rather die than not be together, the possibility of their parents keeping them apart is a death sentence. It is interesting to speculate on what might have happened if Romeo had, instead of buying poisons from dodgy apothecaries, decided to turn himself in, making a clean breast of his marriage to Juliet. What's the worst that could happen? They could kill him. Well, he was prepared to die anyway. And this way he would not go to Hell as a suicide and so might see Juliet in the afterlife. But the disclosure at this point might well have got him more sympathy than at any other time, and possibly a remission of his sentence. In that case both he and Juliet might have lived.
well yes you slept together!
yes
They have all kinds of bad luck. Up until Act 3 Scene 1 everything goes their way. Then in that scene Romeo has the misfortune to meet up with Tybalt, who has been wandering around looking for him. Romeo and Juliet had not publicised their marriage because until it was consummated it could be easily annulled. Once they had slept together, the parents were more likely to reconcile themselves to the marriage. Had Romeo not met up with Tybalt all would have gone according to plan. But meeting Tybalt was the first piece of bad luck. Tybalt's lucky (or unlucky) fatal blow to Mercutio was the second. It could easily have been a flesh wound. Without the dead bodies lying around, the Prince would not have been involved, and even if he was, it was Tybalt and Mercutio who would have paid the penalty for street-fighting. The next piece of bad luck was that Capulet suddenly changed his tune about Juliet's marriage, decided that it was a good idea, and that he could put his reputation on the line in promising that Juliet would agree to marry Paris. It was bad luck that Friar John should not get Friar Lawrence's message to Romeo. Even though the message was inaccurate as to the time of Juliet's awakening, at least Romeo would have known that her supposed death was a fake.
they've definetly kissed but never slept together
It is always possible to alter details of a plot without changing the outcomes. The outcome may become more and more implausible as a result, or the audience may end up sympathizing with the wrong characters. The key issue here is raised by the Nurse. "Romeo is out of the picture, so why not marry Paris?" If Romeo and Juliet had merely exchanged fervent poetry one night in Juliet's backyard, how much would we sympathize with the nurse? Quite a lot, I suspect. If Juliet complained we might see her as petulant and childish. Certainly audiences of an earlier and less indulgent era would have thought so. If Romeo and Juliet had engaged themselves to marry, we might have less sympathy for the nurse. If they had gone through a form of marriage without consummating it, we would have less still. But such a marriage could easily be annulled and certainly would have been if Capulet had found out about it. Once, however, the marriage is consummated, the bond becomes permanent. Once they had slept together and had sex with each other, they were man and wife until death parted them. The church would not annul the marriage nor divorce them. For Juliet to marry Paris would be to commit bigamy, a serious sin. Audiences of a previous time would know this and their sympathy would be entirely with Juliet.
