A Simple Test: Are you wise in God?
A classic verse to check how ‘wise’ His people are:
“and to the married I announce — not I, but the Lord — let not a wife separate from a husband: but and if she may separate, let her remain unmarried, or to the husband let her be reconciled, and let not a husband send away a wife.” (1 Corinthians 7:10 – 11)
You know what this verse implies?
A divorced/separated (‘depart’) person “cannot re-marry” (remain “unmarried”) as long as the other spouse is alive.
P/S:
I know of some pastors (even famous ones) who either teach otherwise or have conducted re-marriages for themselves or others “contrary” to this verse.
Good luck.
