...drop him, her or "it" immediately and turn to God, who will never steer you wrong.
You are never totally "trapped" or "stuck" with wrong advice, taking unwise vows, and promises or courses of action made upon false premises. Drop all of them like a hot potato, do not look back, and look only to God.
God is indeed the only thing humans are, ultimately, "stuck" with, and for that be thankful.
