Where in the Constitution does it state once you join the Union, you can never leave it?

It doesn't.

Correct me if I'm wrong, but I don't think the Constitution even addresses secession in plain language. Does it?

It doesn't.

If our fore fathers were told once you joined the Union, you could never leave it, do you think they would have joined?

Yes

It’s not a suicide pact. And if they intended for it to be irrevocable, they would have said so.
