Not at all. Any culpability that one has can be absolved in Confession.
AND condemn them to a sexless future marriage besides. The church is ridiculous on this point.
In addition to the well-known statement by Jesus, I refer you to Saint Paul:
To the married, however, I give this instruction (not I, but the Lord): A wife should not separate from her husbandand if she does separate she must either remain single or become reconciled to her husbandand a husband should not divorce his wife. (1 Cor. 7:10-11)Your dispute is not merely with the Church but with God's revelation.
Believe what you wish.
