I'll help you out. There's nothing in the Constitution about secession. Any attempt by lost cause fanatics to construct a constitutional argument in support of secession is little more than masturbatory fantasy. Hell, allowing states to secede from the Union would contradict the entire purpose of creating the Constitution in the first place, which was to establish a country with a strong central government that could keep the states in line.
The mere fact that the Constitution was created by delegates of the states did not give the states the right to secede if they decided to take their toys and go home.
James Madison was quite clear on this matter:
And before you begin to think that the line "or absolved by an intolerable abuse by the power created," leaves his position on secession open for interpretation, he was referring not to secession but revolution,
which was a right he believed was reserved by the people, not the states:
Next time you should probably think a little harder before trying to speak down to people you don't know as if they're children. There has never been a right to secede in the Constitution. The states that seceded and those who fought for them committed treason, and did so for the worst of all possible causes. They didn't fight for their freedom against a tyrannical government, they fought to maintain the institution of slavery, itself the worst possible kind of tyranny. They should be universally condemned for their actions, not celebrated as "gentlemen", nor should their actions be rationalized away as a product of their times. Lee's personal issues with slavery are well documented, yet he chose to fight for it. Everything else is window dressing.
