Actually, that's not true.
"If there was any constitutional issue resolved by the Civil War, it is that there is no right to secede." U.S. Supreme Court Justice Antonin Scalia

Scalia: "There Is No Right to Secede"
Your nick is pointless, as we both know, produce evidence for there being provisions against leaving the union, there are none. The confederate 4 left legally sound, they walked into a trap by attacking a fort that the union did not desert as they were required to do, that started the war. They had to do a deal to pay for the fort they attacked, oor make the case that that the union attacked them by no leaving the fort. They attacked, Lincoln got the response wanted, you kept the union. Very simple. Lincoln never questioned their right to leave, just set a trap for them, that they bit. It was OK before that. The confederate 4 would be free today, if they just built a wall around that fort and let it be. Anyways, you are not worth it, going soon, pathetic engagement, putting on a movie or someting if it does not change. Watched a game, over now.
